That was a great post and it helps to clarify in my mind what you're saying.
I'm basically with you when you say we are all God, the cell dividing analogy helps with that. I too am starting to think we are all the elements of creation, walking around, and we're connected because we're all parts of the whole.
I think it's hard, for me at least, to not think of an individual being when I see the word God or hear it. I guess it would be like me saying "elephant" and the first image in your mind is of a twig. This is why "Universe" seems to work for me, it takes much of that religious baggage out of the picture. I'm not sure if I'm ready to accept reincarnation, remember I was an atheist just a couple months ago, and still technically am (highly doubt there was ever a "Big Cheese"). Starting to wonder what the essence of that word is, since I used it to transcend something else, and by doing that, I seem to have transcended it as well.
Seems like you and I are kind of on the same page, it's just that question of what came first, the chicken or the egg. When I think of how insanely vast the universe is, to me it seems much bigger than the concept of a "God" as originator. Reality seems so much bigger than that, in my point of view.
Ultimately, I'd prefer to come to peace with many of these questions in THIS lifetime. I don't like the idea it will take several lifetimes for me to come to terms with this stuff. I started this "journey" of questioning my upbringing when I was around 15, here we are 15 years later and I've transcended much of the lame-ass dogma I was raised with, stopped being afraid, found some sort of peace with the more Eastern flavored philosophy... I think I'm on the right track. Even though I'm going off-track, my posts tend to be rambles. I wake up in the morning and hear myself having conversations with myself about the nature of consciousness, my mind is just rewiring itself.
