There is no proof that god exists, its as simple as that.

You say thoughts don't exist, true, but I know a thought exists because "I can have a thought". Just because its a non physical manifestation doesn't mean it doesn't exist. I know it exists because I thought and experienced it.

God, on the other hand has never appeared to me, never gave any clue to gods existance, I have never experienced god. All you have is a book written over 2000 years by over 20 different human beings. Religion is a massive cult and nothing more. Have you ever experienced god?
