Depends on what do you mean by "God". For me he do Exists and
by God I means "existence".The question now vanishes.
May be "he" pronoun is not appropriate. But "It" is not
correct too because God is not a matter to be called "it".

But I am not an atheist. Because for me "existence" is perfecly
fair and impartial which is not the case with atheists.

Further, if anyone's God is in the form of:
-Mythological invidual God of any religion or
-Many mythological Gods or
-Idol or
-Tree, Flower or
-Earth, Sun, Moon, Mountain, River, Sea or
-Parents, Friend, Other relatives or
-Table, Chair etc etc...

All of them are perfectly right. Because realizing God means
to lose our individuality and thus become more conscious. The
steps of beginning can vary infinitely but they all lead to same
state which we may call "Super consciousness".
