Hey dumbass, the Catholics are NOT Atheists.
And since Pope Pious XII basically said "okay, there's a shit ton of evidence for evolution. WE'RE not going to be the fucking morons this time who deny it for a couple of extra centuries, like we did with that whole Earth is the center of the universe thing," Catholics have even accepted evolution. You'd be an idiot not to. The evidence is staggering.
Or, to use an analogy to science that perhaps you can understand, your stance against evolution is akin to saying "the human body is not made up of cells. Cells are a myth" at a time when scientists are already studying the intricacies of cells.
On another note - I believe the Bible says that God created Adam. Did he create an infant Adam, or was Adam already a man? I suppose we could accurately say that God created a 25 year old (just made up that number, for the sake of argument) who didn't exist until that very instant.
If God created the universe 6000 years old, and if God created man 6000 years ago, then he created a 13.72 billion year old universe (give or take 10 million years) that would be exactly the same as if it had started from a "big bang." And God created man exactly the same as he would have evolved had life on earth started 3 billion years ago and been evolving ever since.
Likewise, the pink unicorn may have created the universe 45 seconds ago. Every memory you have, all the evidence throughout your house that you remember gathering from 5, 10, or 20 years ago never even existed before 45 seconds ago - they're all false memories. Sound retarded? Anyone educated in science finds your claim against evolution to be equally retarded.
