Murchison Meteorite - Life from Outer Space?

So, anyway, apparently I don't have much to do right now, so I'm just typing away here. This post is about the Murchison Meteorite, a meteorite that was observed while falling in Murchison, Australia, way back in 1969. When it was examined and tested, scientist's were shocked (and delighted) to find that it had around 50,000 individual organic compounds (compounds that contain carbon) in it, including over 70 amino acids. The amino acids were found to be racemic (that means that their chirality was equal, or that there was an equal number of right- and left-handed molecules in it). This implied that it did not originate from the planet Earth.


So how did creationist's respond? They rapidly pointed out that for life to develop, the amino acids had to be homochiric, that is, they either had to all be left-handed, or all be right-handed. This is quite a problem for the evolutionist's, but Dr. Ronald Breslow had postulated that "right circularly polarized light in this sector of the universe" may have selectively destroyed all of the right- or left-handed molecules, thereby leaving the remainder homochiric, and therefore fit for the production of life. However, the enemies of this (including myself) are quick to ask what the odds are of such an incident occurring. Also, even if the meteorite managed to crash onto the Earth and "seed" the planet, I have already demonstrated the enormous odds (17^124) against any amino acids, in the most favorable of circumstances, forming by chance.

Please comment if you have a question.
