If the existence of God is not proven, it is therefore false until proven otherwise.
----------------------
Unfortunately God is not a "feeling", no matter how people want to argue this, religion is CLEARLY definitive in their answer on what God said, did, and wants us to do. There is no god "feeling" that dictates religious rules and practices, its written in stone.
-----------------
I don't doubt that a being powerful enough to be called a "god" exist, however it being the religions of humanity's "god" is highly unlikely/false.
