There's a chance that we are actual GODS
Imagine you are a god. You are eternal, beautiful and have unlimited powers to do whatever you want. Every now and that you look at mortals and laugh at their pathetic life. Why should you not? Even a multibillionaire TeraChad is a balding indian janitor compared to you.
But,..after aeons you start getting bored of an existence of eternal power and pleasure so you think it's time to find something really entertaining that would not be spoiled by the fact that you mog the whole fucking universe.
So you think and think when suddenly...eureka! You realize that in orther to find a real thrill you have to nerf yourself and incarnate as a human being.
Of course since you are really bored you rule out the option of reincarnating as Chad or Chadlite as it would pose no real challenge. And being a normiecuck would be too bland.
You then realize you have to play nightmare mode and descending into earthly plane as INCEL. The more subhuman the better! Even better if manlet or with a short penis (optional).
That would explain not only our existence but also why non subhumans lack self awareness and are ultimately NPCs.
It's over for godscels.
