- When you place hydrogen and oxygen together in a 2:1 ratio and provide
- an energy source, what happens? Blooey! Every time? Yes, every time.
- That's the way it is with life chemicals, there is nothing accidental
- about their combination. It's just basic organic chemistry at work.
- We have very good evidence that the primordial chemical mixtures of
- early planetary bodies contain the proper precursor compounds and
- elements in abundance. We know that solar UV and electrical discharges,
- lightning, will supply the necessary energy. We've done it in a test tube.
- We haven't yet made the step to the enclosed cell, but with 10^23 precursor
- molecules in every cubic meter, the combination is bound to occur.
-
- Now none of that implies that Man must be the final result. Indeed the
- odds may be 10^1000 against, though it has happened at least *once*.
- But some form of evolving life is a certainty under those starting
- conditions. Carbon chemistry is carbon chemistry everywhere and everywhen.
