A potential argument for existence of God

[smax]

The universe couldn't have created itself because it was nonexistent before its creation. 

Here is the fundamental flaw in the theist perspective. You start out using a logical deduction but then your very next move is to abandon logic completely. In your view, the universe must have been created because all things must have a beginning, and yet, in your view, god does not. In essence, the universe is subject to logical deduction, god is not. 

The reality is, we don't know for certain how the universe came to be, and I think it's safe to say that our understanding of the universe is still extremely limited. But what we know for sure is, the universe exists, it's verifiable. I personally think the answer of it's origin is vastly beyond our current level of comprehension. But the pursuit of such knowledge is noble, exciting, and capable of furthering many important aspects of civilization. 

The question of god, however, is not exciting at all because there is no compelling evidence that such a being exists, so it seems much like a wasted pursuit that will serve to hinder progress rather than further it. The question of god creates war, suppression, a misguided sense of superiority, cruelty, and fanaticism. Even worse, the question of god threatens the very existence and prosperity of human kind. Because, at the end of the day, it is man who created god and it is man who makes god's decisions. Man decides for god what and who to blow up. Man decides who god wants to suffer oppression and torture. Man decides what people (races or culture) god wants to keep around and which ones he wants eradicated. 

If there is a god, he has long chosen not to reveal himself in any personal way. Why not accept that fact and focus on what is evident. You'll be doing yourself and humanity a great service.
