Not being obviously incoherent is not an argument for that belief being correct; it is merely the very minimum a belief has to achieve to avoid being summarily dismissed for being irrational.

I can understand why you would like the question of why God is necessary to be "misplaced" (which is a euphemism for what, exactly? It is no less coherent than the other questions being entertained here), but, with your 'that's it", you are simply refusing to look further than the answer you wanted.

Furthermore, as I am sure you are aware, 'God' is a loaded term, on which has been heaped a huge amount of conceptual baggage. Therefore, I assume you chose to write 'God', rather than some more neutral term such as 'necessary cause', for some purpose - but what? Your argument for there being a necessary cause would not offer any reason to justify any of that baggage.
