The best proof I can give you Nick is us . The people. How / who else could have created us ? No one but God . It wasn't man made. We the people are the proof that God exists. He created this beautiful world for us to live in.
None. That is why religion requires faith. Without faith, religion hasn't a leg to stand on.
There is no proof. People just follow blindly with a thing they call faith because their lives depend on believing in something. I don't believe in God as man has portayed him but I do however believe in a higher spirit that is not gender specific.
I don't follow anything blindly, except my cute little birdie.
You yourself is proof that God exist. Revelations 4:11 tells us because of him we exists and that he is worthy of our praise.
