Bible says that god created the plants before he created the sun. If that was true, all plants would be dead and without plants we would be dead. That is a much stronger argument than speculations that amino acids couldn't be orginated by natural occurrences, Impaler.
If that doesn't convince you, maybe because you think that it needn't be like the Bible says, then just look at human anatomy. We have remains of a tail!

I hate creatonism!
