Interesting points! In Ancient Aliens documentary, they claim these "intelligent creators" are the so-called ETs (aliens). But regardless of whether that's true or not, one could ask "ok, who created those ETs?" and again, you'd go one level back and should try to find some older intelligent beings who designed our creators, etc., etc.

But this has to stop at some point, because the universe - to the best of my knowledge - is only (!) 13.8 billion years old, thus, some intelligent beings must have appeared some where in the universe long time ago. The question is: "how did THAT happen?" It could be that mere _chance_ resulted in a very early development of intelligent life on a planet in a galaxy far far away. The same process could have helped shape life on the earth too.

Or, maybe there really was an intelligent _being_ in charge of things that designed the whole universe such that exactly a few billion years after the Big Bang, in a specific galaxy and on a specific planet, some certain type of life would appear which would later create other forms of life, and maybe we are created by those people, thus, indirectly, created by that "intelligent being". You may call that "intelligent being" God.
