The Theory of Evolution doesn't have anything to do with the Big Bang. But, then again, most creationists are scientifically ignorant and cannot grasp this fact.
Evolution theory relies on a puportedly random model of one single spontaneous origin for life. So far as I know, no living thing exists without DNA.
I often remind the eco-fascist veggie nazis who say humans weren't "designed" or "meant" to eat meat, that inherent in their statement is the premise there is a designer or some sacred meaning to human existence.
What a lot of people forget when they promote such NONSENSE is the Aristotelian categorical model...
