1. I agree on your statement that
discussing religion is generally a very bad idea on the internet
2. As theology is an ancient field of study, there certainly is a name for your type of belief. I can't name it though, as you did not yet specify if you just believe that God is everything, God is in everything, everything is God or everything is part of God ... I think there are more directions of this but I can't remember what they are called and what the exact difference in meaning is.
