Atheism is irrational.

But, we are here. Therefore, there must be God.

That makes no logical sense. Theists are very prone to not thinking logically, and you are no exception.

Our existence is not a giant magical leap toward god's existence, as you would so falsely like to believe.

On the contrary, the greeks prepared the way for founding natural theology. Hence, new atheists are so wrong in using the Greeks for promoting atheism. What Greeks are against are the mythology, and not the conclusion of Metaphysics which can reasonably and surely show that there must be God.

Your thinking of anything theological is so skewed that it is no wonder you cannot provide a proper logical argument.
