It seems to me that one thing that a lot of religions have in common is a concept of God or Gods that is sort-of, personal. Kind of like making God in man's image. What you describe seems to be more of an impersonal, natural sort of a Creator. It makes me think of what the life and death cycles of bacteria or fungi must be like.
Sometimes I think the best use I can be would be as a very nice, rich compost.
I say that partially tongue-in-cheek, but I think that there might be something to the idea that if you think about death and the meaning of life too much, and you aren't comfortable believing in, forgive me for saying it, fanciful myths, then you will be left feeling very anonymous. And your God will probably feel that way too.
Maybe people have a hard time facing that fact.
