I have my own beliefs; they just don't involve an omnipotent, omnipresent being. To me, that concept just doesn't seem plausible (at least in the here and now... maybe that was once the case, but I'll explain more later). I believe that everything has a spirit.
I also believe that we are here for a purpose... to learn something. And when we have learned what we were sent here to learn, we will move on to a higher state of being. If we don't get it all right in this life, we will be reborn until we have fulfilled our purpose. Part of that belief is also that we came to earth broken... that there are others that have the same purpose as us, and that they are a part of us. That person (or persons) has been sent here to learn the same things as us. And once we find them, what we have learned is united, making it far easier for us to ascend as one than it would be to do so separately. When we ascend to that higher state, what we have learned is joined with those that ascended before us.
I'm sure that just sounds like a lot of hullabaloo and mystic bullshit to anyone who doesn't see things quite the way I do, but that's what I believe. And love, to me, happens when you find your soul mate... when that other part of your soul is found and you connect.
Now here's where I tie into the entire "God" concept mentioned at the beginning... to me, this all-powerful, all-knowing, all-seeing being does not exist. Now as to the why: I think that perhaps this being did at one point exist... maybe even created everything that we now know as our universe, but I don't think that s/he still does. Why? Because life is present. In my belief, the souls/spirits that I have mentioned are basically a shattered consciousness of what may have once been a God-like being.
I see that you posted again before I've had a chance to finish all this... so let me respond to that too.

I think that most scientists that are
completely sure that one theory is correct... are not true scientists. It's a
theory. We don't KNOW for sure, we weren't there. So everything is speculation. The way I see it, you have to take everything with a grain of salt... remember, it was only a few hundred years ago that science believed that the Earth was flat and that it was also the center of the universe!

We've learned a lot since then.
So I'm not saying that I believe in the Big Bang or Evolution or Creationism... these are all views that might be right, and might not, but I'm pretty sure that so far, no one has it completely right. I've studied different religions from around the world for about half of my life now, trying to find what sounded right to me. And as it turns out, I've established that no one religion does. This is why I've taken bits and pieces from different ones until I found something that seemed right to me. Of course, I might learn something tomorrow that changes that a little. To me, it's all a learning process.
Hope all that made a semblance of sense!
