I think this has all been covered, and it doesn’t really address the OP very well, but I’m gonna throw my own 2¢ in anyways! 
Speaking philosophically, as an agnostic, I really don’t believe in certainties, although I’m pretty damn sure I exist in some way or another. Of course it is entirely possible traditional concepts of god are in fact true, but then anything is possible. Possibilities are kind of silly to use when deciding how to perceive the universe. Probabilities are better, and I find it highly improbably that god, as commonly understood, does exist. There is no evidence to support it, other than that a very large number of people believe it to be true.
As a spiritual person, I think of god as being metaphoric. I see god as representing the whole of the universe, everything, and thus I am part of whole greater than myself. I also believe, in eternal life, so long as there is existence you exist, in different forms but essentially we’re all parts of the same swirling vortex of matter and energy. Same for divine plan, I see that symbolizing the laws of physics that govern how the universe works. Etc, etc. Cheesy? Perhaps, but it’s how I like to reconcile religious lore with my personal view of the universe.
It’s not a great leap of imagination to see the appeal of religion. The natural world is a very cruel and frightening place. Tough room if you also see it as being without purpose. And to quote the Master, “…who in his final hour rejoices at the thought, onward to the void?”
If people want to believe in a god to deal with their own personal existentialist angst, well then, whatever floats your boat. It’s only when their gods start condemning people with no reason other than “cuz I said so”, then I start to take issue.
Yeah, consciousness is a tricky one sometimes, but why would it necessitate a creator any more than just plain ol’ matter? I think some people get so hell bent trying to prove that life is so amazingly complex, therefore, there must be a god that they fail to see just how glorious it all really is. Let’s face it, it is pretty friggin’ amazing that we’re here at all. It’s like the question, “Why is there something, as opposed to nothing?” My answer, “who cares?”. Just enjoy the ride and be glad you got to see the show.
