I wouldn't say "He exists" rather "He is" because when you say "He exists" you're saying that there was a time when God did not exist, and this is not what theist, like myself, believe. I believe there is there is a God that He's surely alive.
I'm a theist and at first I looked down to atheists and other religions. Now, I realized I have no right to look down upon them. We are all human and everyone should be looked at equally no matter what your beliefs are.
