Have you ever heard of a concept called 'panspermia'? http://mv.lycaeum.org/mu/_panspermia.html Basically it is saying there is a good possibility that life propagates itself throughout the universe by means of spores. There seems to be an unvoiced assunption that Terra is solely an importer of these spores and takes little notice of Terra as a possible exporter of spores. There is a very high probability that Terra's life forms have been capable of propagating at least bacterial spores for up to three billion years. The universe may be only twelve or so billion years old, and it takes at least a second generation star to support the heavy elements necessary for biological systems. It is relatively unlikely that spore producing organisms could have existed at a significantly earlier time anywhere in the universe. I think that there is a reasonable possibility that the sort of 'yeasty/mushroomy' critters the UFO people call 'Grays' might represent a re-immigration of terrestrial life that may have been evolving independently within the competition free enverons of the comet filled outer reaches of our solar system. aguy2 "There is a high probability that we and the world around us are involved in an ongoing, staged process of self-creation: wherein and whereby the Creator of us and the universe around us is attempting to create itself."
Hum, Well i for one am a believer in panspermia, With exo-life evolving elsewhere and contaminating the earth. (Based on the extremely quick flourishing of life (3.6 Gy) soon after the earth cooled) An alternative is the whole universe should now be contaminated with terrestrial life forms due to the galactic orbit of the sun and meteorite collisions – on a time scale, I believe, less than a billion years… However, the only 'Grays' that i would expect to see would be squirrels...
How are these spores supposed to get from one planet to another? I supposes they could be flung into space by asteroid impacts. But the odds of primordial life getting knocked into space by an asteroid AND surviving in space for millions of years AND randomly encountering another planet that's capable of supporting that specific kind of life in the vastness of interstellar space AND surviving reentry through the new planet’s atmosphere seems...unlikely. At least, it seems less likely than the idea that life simply evolved here in the first place.
Nasor you may be right, but not for the reasons you have outlined. As soon as I cann fiix myy kkeybooard so it sttops doublee ttyping i shalll post a fulller response. (Blobrana, we all know grey squirrells come from Tau Ceti, not the Oort cloud.)
