If you're asking me personally, I believe that they are all the same God. And I do believe in evolution. I don't know all the ins and outs of how and why are here, nor do I believe that god just created man and we were here from the start. The world in 7 days was mans way of making sense of what he didn't understand back then. That's why I dont take the bible literally word for word.
But the idea of there being something that's bigger than all of us, and living our lives in way not to cause suffering to others etc, is something I do take from it. Like I said at the start, it's personal to everyone.
Too many people believe in something, for it to be just be imaginary 'sky fairies' in my opinion. But I respect other peoples opinions, even if I dont agree wth all of them. I'm jus careful about quoting theories, no matter how probable, as facts when you never know if we might find something out tomorrow, that we don't know today, that disproves it...
