>>3Deism = God created the world and left the human beings live their lives without divine intervention. God is not a person and has no super powers, it is a thing.
Theism = God is an entity, and he is the only God (monotheism by default) present. He controls the universe and is always watching us.
In both ways, you are 100% sure that there's a God. But...
Agnosticism = Not being sure if there is a God or not.
There are both the theist agnosticism and atheist agnosticism: I don't now if there's a God, but I do/don't believe there is one.
I hope I've helped.
