Yes... all Gods have been invented for comfort; Gods of fire, of thunder and lightening, of the sea and the rumbling, moving earth. My own belief is that the chief comfort Man seeks is for the great unknowable, death. My own belief is that human existence is merely a sort of playacting, "all the world's a stage," from which we will one day wake -- at death. I think it may be something like waking from a dream; sometimes regretfully, if the dream was a good one, or joyfully, if the dream was scary and awful -- but wake we will one day all have to do.
Can I prove any of that belief? Absolutely not. But it's the best my own limited consciousness can come up with, at least at this stage of my life. I remain open to the possibility of one day understanding more -- which strikes me as the only wise or "spiritual" attitude to have -- openness, acceptance of possibilities, and skepticism towards any human-touted "will of God". You're absolutely right -- we can know no more of the universe than a dog knows of human motivations or constructions. All we can really do is observe -- and understand that our powers of observation are extremely limited.

I respect that, but honestly? The notion that this life is somehow imperfect or just a staging ground for something better strikes me as a little sad. Personally, I think life is the best gift anyone can ever get and it comes off as a little... selfish? that some seem unimpressed and want more.
