As xexious said, it doesn't matter whether it was humans or something else that evolved. It doesn't matter if we have two arms or two legs.
To me, what is important is that higher consciousness evolved, and from our universe and all our random and non random processes... higher consciousness
To me--the immaterial consciousness (energy of our being/awareness/thoughts/emotions) is linked to the immaterial Spirit. To me, that energy is "God".
For myself, I view this consciousness energy, when the brain goes off (dies), as a natural echo that lingers. That is what I think often people see when they see a Spirit.
It is possible this echo fades, but I tend to think it becomes interconnected with all things and all that in Nothing.
I think when people say "God" what that really is, is EveryThing and NoThing. The natural and the spiritual. All our consciousness (this includes animals and aliens) all linked as one with all that is immaterial, and all will return as one in space, time, and energy again. Then, it will all possibly be reborn again and do it all over again, but physically differently.
We've probably been through this so many times it is crazy to think about...
For myself, religions try to understand the spirit while the sciences try to understand nature. But both get it wrong a lot and neither has a perfect model. Reality, in my view, will always be just an echo away which we can never quite grasp...
But perhaps we are getting there.
