Here's some things to consider:
First, our ability to be self aware has clear evolutionary self-preservation benefits. Knowing where we are and what we're doing and predict the future can save our lives. Thus, natural selection prefers complex brains that develop the ability to abstract as a powerful survival tactic. Like so many genetically inherited mechanisms, we often use these mental tools in other ways that aren't particularly beneficial to our survival. Postuating our position in the universe isn't going to save us from being eaten by a tiger but we have that skill so we use it. Another example is recognizing faces. We're all born with the simple ability to recognize faces. You might wonder why we often see faces in things that are not faces (clouds, wood-grain, grilled cheese sandwiches). It's because knowing a face is a survival technique and is hardwired into our brain because it's a survival tactic. The more a face looks like your own, the safer you are with beings with such a face. The more "alien" the face is from your pre-programmed pattern of safety, the more we fear it.
Second, we are all made of star stuff. Do you really need a supernatural selection process to explain why anything is anything? Shit happens, dude.
As any atheist would be quick to point out, using "God" to explain what we currently don't understand about ourselves (where in this case at least I feel like we're at the beginning of grasping it) isn't really an answer. It's a scape-goat. It's a non-answer. You'd be much wiser to simply say "It is yet to be explained" than to take the less logical and more cowardly route to invoke the non-answer that "God did it". Since God is not itself explained you've not answered the question you set out to answer. Humanity needs more humility to just admit we simply don't know. We may never know.
