In the beginning, a group of proteins and sugars came together. Long story short, out of this soup, the kingdom of mammals--of which I am a part--governed by a code of nucleic acids managed to survive to a high level of development. Luckily, even though only a small percentage of this code is actually useful, useless code just happened to insert into the genome without disrupting the production of proteins necessary for existence. Luckily, despite the presence of millions of asteroids located in our cosmic neighborhood, organisms were allowed to pass this code along and mutations kept accumulating until primates came about. Luckily, one of these mutations just happened to result opposable thumbs, which gave an advantage to a rather frail fellow. Luckily, he gained enough higher brain function to able to make tools capable of killing animals significantly stronger than himself. Thus, a weak freak of nature established dominion over his world.
Don't get me wrong, all of this is plausible--I'm not trying to discredit evolution. But something which owes it existence to a string of coincidences surely doesn't have the right to worship itself. People don't necessarily need religion, but, for crying out loud, need to accept their place as the result of 4.6 billion years of evolution.
