People have been worshipping Zeus for thousands of years. People still do in Greece to this day. There’s lore about him, people have “seen” him in visions, dreams or hyponagogic hallucinations or whatever you want to call it, and there are hundreds of stories about him.

Same goes for thousands of others Gods. People have felt them in their hearts, seen them and sacrificed for them.

What makes your God more likely to exist than all of the others?
