Who is God?

Wow! What a way to start a blog. But, this is something that has really been pressing on my mind lately. I have actually allowed myself to really question the existence of God. I was brought up in a religious home and was quite active in the church for awhile. However, the question of the existence of God has been in the back of my mind for much of my life. So, to make a long story short, I question the existence of God. I don't know if a deity exists or not, but tend to disbelieve.
