Also lack of belief in god/intelligent design, is not a clam that they don't exist. Shit some people claim we were put here by aliens, or that we live in something like the matrix, where reality is like a computer program, or that everything is really a hologram, or on and on and on and on.....
Big deal, where is the solid evidence to any of it? You haven't provided any Fusion. There are all sorts of fantastic ideas as to what it all means, and how it all got here, the sad thing is that some of these outlandish things have more evidence to their probability than YHWH!!!
Instead of coming up with an end BELIEF, then trying to make any plausible possibility fit into that believe why don't you start at the other side, what does evidence show without any preconceived idea.
Here is something of value from Hawking FusionTheism
“When people ask me if a god created the universe, I tell them that the question itself makes no sense. Time didn’t exist before the big bang, so there is no time for god to make the universe in. It’s like asking directions to the edge of the earth; The Earth is a sphere; it doesn’t have an edge; so looking for it is a futile exercise. We are each free to believe what we want, and it’s my view that the simplest explanation is; there is no god. No one created our universe,and no one directs our fate. This leads me to a profound realization; There is probably no heaven, and no afterlife either. We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful.”
