There are theories for that, that so far we haven't the technology to devise observable experiments.

And if no matter how far you go back it requires an answer to the question "how did that get there" I don't see how it ultimately requires a creator because that just moves the question to "how did the creator get there?" So far, every time we've moved "creation" farther back it has been through evidence of another new physical process. I don't see where continuing that chain eventually requires a sentient process of creation.

It took millenia for mankind to realize that time is not a constant and the mathematical basis on which it is relative to perspective. Perhaps it will take another 15 millennia for someone to figure out the process by which the initial conditions of the universe came into existence. I still see no reason to simply assume a non-physical process.
