Since god isn't defined, the only way I can define it per this OP is something that isn't detectable to the five senses. Like L/S, god in this sense all three cannot be detected. There is a lot written about them, though. Of what people think what they look like, do, how, and their position in the universe, etc. So, they have that in common.
Though, I can't see how comparing the two disproves one is much more different than the other. That fallacy doesn't seem to ad up, no?
This is why I am of the opinion that there are more than one God. Because as it stands, there are millions of accounts of deities around the world (and they help in differing ways), in all traditions and sects, and even amongst the non-religious. Multiple descriptions, equates to multiple Gods IMO. But maybe this is off topic?
To answer your question I hope, I was mostly skeptical of the Gods existence for quite some time, until they made their presence known to me. And I think that is because the Gods are not "seen" in the traditional sense, they are Felt.
