Proof is a manmade word and not one that can be utilized in the defense of anything!

The REAL burden of proof is on God (not us), and He has proven Himself in many ways, that is why we believe. Design is one way He has proven Himself. I mean, think about this: Your stomach contains some acids that are strong enough to burn through metal...yet you STILL have a stomach. It is because God DESIGNED it that way. He designed your stomach lining to secret mucus that neutralizes these acids at the lining to protect it...evolution didn't do this, design did this. And this is just ONE of the BILLIONS of proofs that God exists.
