an atheist is someone who doesn't believe in a god.
A person who believes that the universe and everything in it is God, rather than created by a god or gods, is called a pantheist.
A Believer =) a cristian or a jew. And Muslims.
I would call him a god, or at least someone who believes he is a god.
The antonym of atheist is theist. An atheist is someone who does not believe that god(s) exist, or that there is no reason to believe that they exist. A theist is someone who believes that god(s) exist and that there is sufficient reason to believe that they exist.
Agnostic
Christian??
Theist is the word you would use, as opposed to atheist. Religious people can be theists as well, but theist is as general as you can get.
An atheist is a person who believes that there is no God. An agnostic is a person who is not sure whether or not God exists or who believes that we cannot know whether God exists or not.
For religious people, God. God would have to be the most well known person ever. Every religious person in the world believes in some sort of God no matter the name they call him or her. Even if your not religious you've herd of God.
There is no such person. An agnostic is a person who believes that it is impossible to know/or is skeptical about the existence of God but does not profess true atheism. A Christian is a person who believes in the existence of God and has faith in God. So the phrase a 'Christian agnostic' has no meaning
Islam says God exist and there is no God but Allah. Hinduism believes in existence of multiple Gods.
Monotheistic, or a monotheist.
