BS. Postulating that life on Earth arrived through a meteorite pushes the explanation for life on to an impossible-to-determine other planet.
Stupid.
It arose on Earth.
Hey! What happened to the old chestnut about the comet that hits the Earth, melts, and then a bolt of lightning starts the Life Cycle chain???
But I have to agree with you. It's ironic that we have to have faith in these scientists that (the seeds of) life began somewhere else, was blown into outer space, and somehow found our world.
Yeah! Yeah! That's a LOT easier to swallow than a belief in God! /s
It's always something--anything--else.
Since nobody knows and the evidence was eaten, such an assertion is not disproveable. FR would shrivel up and die without such non logic.
By U/Pb-Th/Pb isotope ratios it seems that meteors originiated concomitant with the Sun. Thus those scientists who will, are left with still having to thrash about to discern what God wrought. Though I doubt they ever will, since discovering life’s beginnings necessarily also means discovering its end.
It’s not a stupid postulation, just far fetched.
Not life. Amino acids.
We have seen amino acids come down on meteorites, and form naturally here on earth.
Nothing mysterious about amino acids, but it is interesting that polarizing light in space could preferentially destroys the right handed amino acids rather than the left ones.
But it is a rather weak explanation for the prevalence of left handed amino acids in terrestrial life forms.
