There’s nothing terribly new in this article. Meteorites are being found all the time.
There’s one show I watch about two guys who hunt meteorites, and they go out into the desert, or some farmers field, and walk around with a metal detector, and dig up a rock and say “Ooooh, isn’t that a beauty, I’ll bet we get a thousand, maybe two thousand dollars for that,” and I think “Dudes, that’s not even going to cover the cost of your trip, do you have real jobs, or are you getting paid a lot for the TV program, or what?” I enjoy the programs, I’d a lot rather watch guys digging up rocks from outer space than a bunch of guys in creepy, fake country western outfits and mustaches fight over the contents of a stupid storage garage. It’s just that the math doesn’t add up. First, I’m a little bit surprised that such a thing can be purchased at all – it seems they should all belong to museums, or high powered science labs, not sitting on some collector’s shelf, somewhere. But, since they apparently can, I’m surprised that they aren’t worth millions, and not thousands (or even hundreds, the smaller ones.)
Anyway, the article touches on the old argument that life on Earth did not originate on Earth, but came here on board a comet, or asteroid, or rogue rock that eventually became meteor, meteoroid, and meteorite. I’m not convinced. Life could have evolved on Earth because we’ve got water and sunlight, and that seems to be all it takes, and we’re not even so sure sunlight is required, any more. Life could also have evolved on other planets and come here on an asteroid. I’m ready to go with Occam’s Razor on this one, until proved wrong.
That doesn’t mean I think we are alone in the universe. I believe other, intelligent, technological species are out there and some day we will find them. If we don’t, we will just boldly go colonizing the galaxy until we do. Whether we originally evolved on Earth or as a space bacterium of some sort, evolve we did.
And there’s no limit to where we are going.
