Germs from Space

In the original “War of the Worlds” novel, our Martian invaders where thwarted not by us high and mighty humans, but by humble terrestrial bacteria who just ate them up! The question therefore is would extraterrestrial ‘bacteria’ find us (terrestrial life) a nice snack? The answers could be both ‘yes’ and ‘no’.

The War of the Worlds Scenario:

No, I don’t mean by this that there is any analogy between the UFO extraterrestrial hypothesis (ETH) and alien invasion, a typical example being the “War of the Worlds” (be it the original novel, the movies, the TV series, the musical, etc.). I refer here to the ultimate resolution of that alien war scenario – that ultimately what defeated the Martians were terrestrial microbes – bacteria to which the alien invaders had no resistance. That was a really excellent plot device – it was also lousy science! If there is one truism in biology, it is that cross-species infection is rare. There are of course a few exceptions to the cross-species infection rule, but they remain by far a minor, minor, minority. Micro-organisms tend to be species specific in terms of their nastiness. Thus, if I sneeze, my cats aren’t in any danger of catching my cold – and vice versa. I’m not about to infect any of my garden plants by touching them with my dirty soiled hands – I’m not likely to become infected with a deadly disease from a maple tree. If a wild bird has beak and feather disease and my cats should happen to catch and eat it – well, the bird was doomed anyway, and I’m not going to have to rush the feline predator off to the vet for shots! So, if it is relatively unlikely for one terrestrial species to be a contagion towards another terrestrial species (unless they are very closely related – evolutionary speaking), then what odds a terrestrial species will be deadly to an extraterrestrial species – and vice versa.

What’s the point of all this? Well, if UFOs can be explained by the ETH, then it is unlikely in the extreme that the ETH exists in a species vacuum. That is, ‘ufonauts’ (for lack of a better term), more commonly known as ‘the greys’, will be associated with their extraterrestrial micro-organisms (maybe ever their extraterrestrial equivalents of head lice, mites, bedbugs, cockroaches and rats depending on how hygienic they are). We do not exist in a bacteria free environment, nor could we even if we wanted to. ‘Ufonaut’ bodies and their UFOs will be as ‘bacteria-ridden’ as our bodies, our homes, automobiles, and in fact any and all other bits and pieces of our environment. We haven’t endured or experienced any pandemic or epidemic due to micro-organisms associated with ‘ufonauts’, and presumably ‘ufonauts’ haven’t caught cold or smallpox or the measles from microbes associated with us, our cats, birds, or any other terrestrial life forms.

So, UFO sceptics can’t invoke the “War of the Worlds” resolution as an argument that the UFO ETH is an invalid one. So, by all means, shake hands with an extraterrestrial (ET - if you meet him/her/it) and don’t worry about any resulting medical bill – it ain’t gonna happen.

However, this does open up an interesting research area – one I’ve never, ever, seen mentioned in the UFO literature. That is, extraterrestrial microbiology. If UFOs are piloted by alien beings, biological beings that must be associated with extraterrestrial micro-organisms, then presumably said ET microbes have entered into our terrestrial biosphere. Presumably, said ET microbes would be so biochemically distinct or unique that any microbiologist examining same would immediately note that something was afoot! Of course, if you’re not looking out for it, you’re unlikely to find it or get that ‘eureka’ moment even if you do find it. Perhaps UFO abductees or UFO landing sites should be examined for the presence of extraterrestrial microbes.

So what then to make of the late Sir Fred Hoyle’s et al. claims or ideas that some of our terrestrial disease outbreaks originated from outer space? It’s a variation on the panspermia idea – life on Earth originated from extraterrestrial microbiological life forms seeding our planet.

The Fred Hoyle Scenario:

It’s well established that interstellar space is full of gas and dust. What came as a surprise was the unexpected discovery that many of those interstellar regions are also rich in organic molecules. Organic means that the compounds contain carbon, one of the elemental building blocks central to biology – along with hydrogen, oxygen and nitrogen, also well represented in interstellar gas and dust clouds. Many dozens of organic compounds have now been verified in the reaches of outer space, more than a few highly complex organic molecules, many associated in one way or another with life and biological processes.

Also verified has been the discovery that actual life forms, albeit simple microbial ones like bacteria, can, if not thrive, at least survive the rigors of outer space with minor shielding (say dust particles) to protect again harmful radiation. Terrestrial bacteria have survived three years on the Moon as demonstrated when the Apollo 12 astronauts brought back from the Moon pieces of the Surveyor III Lunar Lander, which had landed on the lunar surface three years prior. Experiments in Earth orbit have confirmed that some terrestrial microbes can boldly go in the cold and vacuum of space. 

Not so verified, but highly plausible, is the idea that simple life forms can be transported throughout the galaxy, hitching rides on dust particles, even larger objects like small hunks of rock that were ejected from their home planet. Recall the Martian meteorite (ALH84001) found in Antarctica which showed various lines of evidence that it was home to ancient fossilized Martian microbes. The controversy over that still hasn’t been resolved to the satisfaction of all.

Comets are known to be rich in organics, ditto some asteroids, and some have claimed that debris, say chips of an asteroid that have impacted and landed on Earth as a meteorite have ‘organised elements’ inside them suggestive of unicellular life forms. The possibility of course exists that those ‘organised elements’ were terrestrial contamination, since it can often be a long time between the fall of a meteor, and the discovery and analysis of the meteorite it became.   

The late Sir Fred Hoyle, along with several colleagues, most notable of which was Chandra Wickramasinghe, went a few steps further. Not only were there simple life forms in the depths of outer space, not only could they have seeded suitable planets with life – like Earth – but they to this very day rain down upon us. Further, they provide a far more logical explanation for various epidemics, maybe pandemics, experienced here on Earth. Why should some of these extraterrestrial bacteria be potentially infectious to us?  Well, if these microbes are the same sorts of microbes as seeded Earth ‘in the beginning’, that is were responsible for kick-starting life on Earth; providing the origin or life on Earth, then we share a common ancestry with them. We evolved from them over all those billions of years. Looking at it another way, we, in fact all life on Earth, really isn’t terrestrial life, but extraterrestrial life. We are the aliens!

Anyway, how does it happen? Specifically that is, or at least one mechanism, Earth’s orbit intersects now and again a stream of bacteria-laden cometary dust and debris – germs from outer space – that impact Earth’s atmosphere and ultimately filter down (perhaps incorporated in rain drops) to ground level and do their infectious thing.

However, to be fair, to state that their ideas are controversial is very definitely an understatement. For their side of the story, you’ll need to examine the evidence they present in there books (see further readings).

So, is there a conflict with extraterrestrial bacteria escaping out of a UFO and having no impact on the terrestrial biosphere and extraterrestrial bacteria arriving from interstellar gas and dust clouds, or cometary and/or asteroid debris? Well, there’s no conflict IMHO. The two sources of alien microbes are just that – two independent extraterrestrial sources that have no connection with each other. Of course relatively few experts in infectious diseases give any credibility to Hoyle’s theory so that might eliminate that. Then too many scientists don’t give any credibility to the UFO extraterrestrial hypothesis (ETH), hence to alien microbes originating from that source. However, whether none, one or both ideas have or lack credibility doesn’t result in any ultimate contradictions.

Extraterrestrialism: Part One

If asked the question about your ultimate origins, you might reply that you were of this or that nationality, perhaps with ancestry from this or that other place. Perhaps if you’re a bit more clued you’d say “Africa” as the birthplace of the human race. If you’re really cluey, you might say the oceans, the undoubted place where life itself got its start. But no doubt, no matter what, you’d say you were “terrestrial” – of this Planet Earth. Alas, you’re still not cluey enough. You’re extraterrestrial. We are the aliens, directly and indirectly.

Origin of the Universe

* Once upon a time there was this Big Bang.

* Since we are a part of the Universe, and since the Universe had an origin (the accepted standard model being the Big Bang event some 13.7 billion years ago), that alone of necessity means we have an extraterrestrial legacy since everything that makes you, you was born in that event, thereby in a manner of speaking making you 13.7 billion years old!

Origin of Our Stellar Solar System & Earth

* As it was in the beginning, well so too did our Sun and Planet Earth have a beginning.

* We are Star Stuff. Our solar system, our Sun, the planets, including Earth, were all formed out of the remains of extraterrestrial gas, dust and debris from older stellar systems, scattered to the four interstellar winds by supernovae explosions, over four and a half billion years ago. Thus, that too alone, no matter which way you slice it, means we (as beings part and parcel of our stellar system) are extraterrestrial in origin.

Origin of Life

* The terrestrial origin of life may have happened within that petrii dish/test tube called Planet Earth - Or maybe not. IMHO it happened way too quickly and way too soon post Earth’s formation to probably have been a solely terrestrial happening. There’s an alternative called panspermia which expands both the time and space available for life’s origin by many order of magnitudes.

* Panspermia is the idea that Earth was seeded by cosmic spores or microbes that were expelled from some other planetary abode in some other stellar system and drifted across the gulf of space. An incredibly tiny fraction of these cosmic spores lands on suitable planetary environments, where they survive and thrive and evolve. Our Earth was one such place for their lucky landing. It’s akin to a plant producing millions of spores – 99.999% of which fail to land on fertile ground; but that tiny fraction that does is all it takes to keep the species keeping on keeping on. 

* Ballistic panspermia is a slight variation on traditional panspermia in that the microbes or spores are inside the protective covering of a solid object – dust or tiny rocks, even massive rocks. These, alone with their microbial passengers get blasted off home turf by incoming ballistic objects (impacting meteors), escape their home planet and a few eventually, by chance land on another suitable abode. That Mars rock, ALH84001 that caused such a stir several years back is one such example of a potential case history of ballistic panspermia.

* Directed panspermia is yet another variation on the theme, only in this case there’s intelligence behind the scenes, either sending out canisters of microbes willy-nilly in a shotgun manner, and/or directing that canister specifically at a chosen target.

* The upshot is if terrestrial life’s origin was via a form of panspermia, then we humans, being a species of terrestrial life, ultimately had an extraterrestrial origin. If a Mars rock full of microbes impacted Earth billions of years ago, well, we might be the Martians transplanted from the fourth rock to the third rock from the Sun. Perhaps our origins were even farther a-field. Perhaps some cosmic gardener planted life here billions of years ago, maybe even stuck around to fertilize, cultivate, prune, and weed that garden. 

Extraterrestrial Life, Intelligence, Civilization and Technology: The Fermi Paradox

* The Fermi Paradox can be summed up simply enough by pointing out that as long as you assume the existence of at least one other technologically advanced extraterrestrial civilization with the same sorts of ‘boldly going’ drives as we humans have (i.e. – plain old curiosity, the what’s on the other side of the hill, if nothing else, then just as humans explored and colonized Planet Earth in a tiny fraction of the Earth’s existence, technologically capable extraterrestrials would have explored and colonized the Milky Way Galaxy in a tiny fraction of its existence. In the case of humans, we don’t need to ask “where is everybody?” We’re everywhere. In the case of ET, we do ask “where is everybody?” They should be here. Scientists say they’re not, never have been, and thus have to explain the paradox. On the other side of the fence, those who see evidence in those ‘ancient astronauts’ and in UFOs have no paradox with which to have to come to terms with.

* The ‘Gods’ arrive. Very few people today would try to defend the position what in the vastness of the cosmos we, human beings, are the proverbial intelligent ‘IT’ within that cosmos. Since we are the new boys on the block, having only existed as a unique species several hundreds of thousands of years at best in a Universe that’s 13.7 billion years old, the odds are pretty good that our intellectually cosmic superiors are out there. Now on the likelihood that at least one such superior extraterrestrial intelligence will boldly go and explore the cosmos, let’s define ‘cosmos’ and restrict that term to our ten billion years old Milky Way Galaxy, the time it would take that extraterrestrial intelligence to explore every nook and cranny of our Milky Way Galaxy is but a tiny fraction of the age of our galaxy. By analogy, Planet Earth has existed four and a half billion years; yet as noted above our 100,000 plus year old species crawled all over it in real quick-smart fashion, as did the bacteria, plants, insects, and other life forms as well. Translated, since there’s nowhere to hide Planet Earth from the ‘I spy with my little eye’ aliens, we’ve been found! The extraterrestrials have arrived, not yesterday but millions of yesterdays ago. And since Planet Earth is a hospitable bio-friendly place, one with a pretty unique property – a biosphere – they decided to stick around and set up camp. Because these beings are high-tech, and because any sufficiently advanced technology is something supernatural to any sufficiently lower technological civilization (like us), that supernatural quality gets interpreted as beings who ARE supernatural – deities or ‘gods’ – not interpreted by the great unwashed primitives as flesh-and-blood extraterrestrials. Our cultural mythologies, worldwide, are full of references to ‘star beings’; ‘guardians of the skies’; ‘sky gods’; ‘gods in the heavens’ and gods who come from the stars or who are associated with specific stars and constellations, most notably Cygnus, Sirius and Orion.
