No. I'm a nonreligious philosophical theist. (Strictly speaking I'm an agnostic, but if you consider agnosticism as a spectrum or range of views between atheism and theism, I'm well over to the theistic end.)
If so, do you believe God had anything at all to do with how human beings came to exist?
I tend to believe that God had (and has) everything to do with how everything comes into (and continues in) existence.
Or, to put it another way, if God did not exist, would we be here?
I suspect that the world is dependent on God for it's continued existence. If God were to cease existing, then so would the world.
At the same time I suspect that, while God freely and unstintingly gives the gift of existence to all things, that he also allows them the freedom to exist (and evolve) according to their nature and circumstance. I suspect that, to whatever extent God governs the universe, He does so in a manner that is seamless with respect to the authentic nature of all things, so that the universe will ultimately appear to be complete and coherent from the "naturalistic" perspective. IOW I don't think He uses "miracles". Except in the sense that existence itself is divinely grounded, so that literally everything is "miraculous" to begin with.
Now, since God is distinct from his creation, then there are (at least some) aspects of God that transcend the world. So there may be some "seam" at the point where you pass from the creaturely realm to the divine realm. But I'm not convinced this seam will be visible, or at least readily apparent, from the creaturely side of things.

I concur! I thank you for being so open about your views.
