You surely have to at least give the benefit of the doubt that a God may exist.
This is true, and I do.
Nowhere in any of these statements have I said there is no chance of a creator, or even that there is no chance he's exactly what you think he is.
If God is what you think he is, what you have described, then he mostly seems like a cool, chill guy and I would have no issues shaking his hand and generally being friends. But quite frankly I consider the sunshine butterflies and rainbows picture you have painted to be EXTREMELY unlikely.
If God is real but NOT what you think he is, but what he is literally portrayed as in the Bible, he is NOT in any way shape or form a decent person and I am very much not cool with him overseeing the universe. Given what little evidence we have, I sadly consider this more likely then your personal viewpoint.
This is why I consider myself an Anti-Theist instead of the more traditional Atheist. An Atheist is someone who at some point said "I don't believe God exists"
Whereas an Anti-Theist such as myself at one point said to themselves "I don't believe God is good"
This doesn't mean that I don't believe in the POSSIBILITY of an Omnibenevolent God, just that I don't believe in the LIKELYHOOD of it.
Basically if God is as you think he is, then my statements so far don't matter, because he's not the bastard I think he is.
If there is a god who is totally indifferent to our existence, also a possibility, then it doesn't matter.
If The Bible and everything in it are poetic and metaphorical and all that, it doesn't matter because it has as much bearing on reality as Mickey Mouse cartoons.
If God doesn't exist well DOESN'T MATTER OBLIVION FOR ALL. Which I would be ok with personally.
If however, The Bible is literal and real and the God depicted in it is the incredible bastard he is written to be, then I have a problem and recommend investigating anti-deity weaponry. Which I'm working on just in case.
Point is, I don't know how the universe was created or what happens when we die. I'm just the type who prepares for the worst.
