To your first comment, what point is there in suggesting that "we are, in effect, our own gods"?
Your comment seems to beg some unasked question or to press some unnamed agenda.
I have no requirement for gods. It appears that nature functions with complete independence from your gods or anyone else's gods.
If you have a desire to be your own god, have at it.
Human culture has a history of inventing supernatural entities to explain that which we didn't understand or that which we could not readily explain. When there was a gap in our knowledge of processes or mechanisms, it was tempting for societies or cultures to abandon pressing deeper for knowledge and to accept the easy (and lazy) alternative of defeat and say 'god did it' (or more often 'the gods did it').
As to your second comment, I'd suggest biology 101. Cell biology is plagued by replication errors and faulty coding. Doesn't that speak to an Incompetent "designer" as oppossed to an Imperfect nature?
Honestly, you could easily have done your own homework and discovered these answers.
So, we make our own plan, determine our own fate, build our own world...up to the point of death. THAT we have no control over, but everything else we do. We create our own reality.
I've known an awful lot of people who subscribed to that theory, whether they could verbalize it or not, and most of them invariably ended up staring off into space and wondering what the hell happened. They had it all figured out, had their lives planned to T, but somewhere along the way it all fell apart and left them empty. Even those few who managed to succeed, against all the odds and the vagaries of time and fate, still got to the end of their lives and found they'd accomplished....nothing. Having won all the battles and collected all the toys, they stared into the open grave and wondered if they'd wasted their lives in the vain pursuit of selfish goals. The answer is yes, they did.
But, you don't see that yet. I'm guessing you're fairly young, or old and still terribly naive, and have not yet butted up against the reality that in truth, you control very little. Control is an illusion, a tempting and satisfying illusion, but still a just mirage.
Good luck. I hope I live long enough to see how it turns out for you. If I'm not here when the lie of control is finally revealed, please do what millions before you have done when their path stopped at a dead end: turn to someone of Faith. They'll have the answers you need then, and only them.
