This is the inevitable conclusion if you consciously deny the existence of God.
The position of 'denying the existence of God' is fraught with problems. To deny the existence of something means that one is certain that this something doesn't exist. Yet many atheists, including myself, do not take a position of certainty at all. I simply lack a belief in any god, which obviously includes yours. Science demands evidence for its findings, but every conclusion is considered provisional because of the possibility of new evidence which may alter prevailing thought on any scientific conclusions. I take a similar approach to the idea of a god. To date, I have found no evidence which even goes goes part of the way in establishing the existence of your God, or any other god, as an unassailable certainty at all. This, by the way, includes all your 'jigsaw puzzle' pieces, where any objective evidence at all is noticeably absent, either on an individual piece or a cumulative basis.
What I have found is that, for instance, explanations for the development of life on this planet, on the make-up of the universe or even my personal well being don't need a god as an explanation. That is not to say that a god doesn't come into this mix, but simply that there is no evidence for and no need of a god. Furthermore, simply to say we do not know how life began, or to say we do not know what(if anything) came before our universe began, does not presuppose a god at all. All it says is that we do not know. For a god to have any value at all, then it would have to explain all these 'don't knows' in detail, with accompanying evidence as to why and how this is so.
Hence to finish, my position is clear, at least to me. I do not deny the existence of any god, but I see no good reasons why I should bother with believing in one.
