The odds are indeed slim that chance would assemble a self-replicating protein, or whatever. But the more molecules you have bumping up against each other, the greater the odds of that happening somewhere, yes or no? --RG
Is it reasonable to assume that our planet is not the only planet this universe with liquid water?
Is it then reasonable to assume, based on currently available data, that the number of planets with liquid water is very large?
Then that number of planets, both past and present also provide chances for simple organic molecules to form?
