To me, God is what animates us. Love, music, aesthetics, nature, etc, i.e., the things that move us. What do you think?
For me, God is the simplest and most natural explanation for existence, and perhaps why so many readily take to believing in such.
However, given we humans often do have the intelligence to question and learn, it seems as well to do some work so as to eliminate all other possibilities before having such acceptance. Many are not bothered and/or will be satisfied with one of the numerous explanations and descriptions of such a God (and hence will often have a religious belief), but many will not be, and hence will have to research and find suitable answers that can explain as much as the easier God explanation might.
Who knows as to why some feel the need to find other answers and where many don't, but eventually it all boils down to either accepting one version or the other, especially when there are just as many reasons not to accept the God explanation as there might be to believe such.
Oh, and I mostly don't believe in God or gods - given that I have found enough evidence so as this not to make much sense.
