Okay, dude, take your own advice, only reversed. Push all of your evolution knowledge into a small box and then step away. Between unstartable replication of DNA to the unevolvable flagellum motor on a bacterium, The whole theory finds itself breaking down, starting up again, and then finally colapsing from the inside out.
Now, step into that religion box, and imagine that there really is a God, and more importantly for this topic, a devil. Say that you are part of a religion. Any one religion. Now you look around inside that box, and you see all the other religions taking people down to heck. Now remember, only one religion can be right. Say it happens to be yours. So if there is only one true religion, then the others OBVIOUSLY were started and created in the minds of men by the devil, right? I mean God didn't create any religion except for the right one, right? So here's my point. Looking at all religions from a non-religious stand point seems to make them all look contradicting. But if you are a religious person, who believes in God and a devil, it is easy to see why There are so many different religions in the world. But you must try to be a believer to understand this.
That's how a religion can make that claim. Being of the LDS, or Mormon religion, I can see this very easily, especially since I know that my church was RESTORED to the earth, rather than being around forever, and leading people away from Christ and his gospel.
So that's that, and there you go.
A Day unto God is thousands of years to man. 6 Godly Days of creation does not undermine the fossil record.
The fossil record, however, clearly undermines evolution. (Any questions should be asked, and every answer will be given)
