You are free to believe what you like. However there is a burden of rationality inherent in conversation particularly public ones. Advancing arguments of a god should require that you engage with the following:

1. Posit a set of axioms that exclude sought proof.
2. Define god. 
3. Define existence. 
4. Show objective evidence that a god meets that criteria.
5. Show that the result is significant! 

IMO.  Morality, just like god is likely a construct. It is an very important one, but a construct none the less. Arguments that rely on the most good, or the absoluteness of good are flawed. Humans certainly do not seem to be divine or special in any sense. It seems likely that we are simply cleverer animals. The initial formation of the universe is outside the boundaries of concrete knowledge. However the formation of the universe while including randomness, is not random.
