The fact is that god is not a scientific theory, hypothesis or anything, it's just religion. It's by definition something that you have to believe in based on faith, not evidence, which is what everyone does. Faith is not a good path to the truth, that's also a fact.
In my opinion, the experiences with God are not necessarily based on faith or belief. Some people have experienced true, personal, life changing miracles that prove to them God is real. To them, they don't need to believe in God, they know God exists.
