All gods ever claimed to exist were claimed to exist by humans.
Of the thousand or more god-concepts that are claimed today, right this very second, most contradict or nullify the others. All the claims we have ever seen admit that their god is not detectable from the human perspective. Each god requires you believe on faith, meaning without material evidence. Normally humans don't do that. Normally we check our bank balance to know how much we have. We don't bank on faith. Presumably,banking is not nearly as important as how you relate to the entire universe... so you would really want some solid evidence before picking one of the 1000 current (or the thousands of previous) gods to believe in without evidence.
What to do?
Your best bet is to reject claims of Allah, Shiva, Jehovah and L.Ron's Ghost until such time as there is a shred of evidence for one of them. You can't, as the church lady will admonish you to, rely on faith. Which one do you have faith in? The one that's popular geographically? That's for Kardashians, not for omnipotent creators of space and time. Nope.
You just have to take the default position. That makes sense, right? If one of these claims is true, or there is a god who has not yet been defined, you would think and hope that they would appreciate your intelligence and patience in the matter of that discovery. If that space monster blames you, he/she/it is an asswipe.
In the meantime, ain't nature grand?!
