Evidence God Exists

[DR7164]

I think this is an argument that has probably been used a couple of times and is a favorite by a lot of atheists but here it goes anyways:

Why is it that your evidence points to God's existence?

I have a book here at my home that is even *older* than your book and it says that all of your evidence points to the existence of an alleged one-eyed-purple-people-eater, so what makes your evidence point to God's existence rather than the purple people eater's existence? But a one-eyed-purple-people-eater in the sky couldn't possibly exist right? That's just nonsense.

I'm not mocking, just using an example
