Why would God require us to sleep?

That is, in my (19m) very much mortal opinion, God's single greatest mistake of creation.

I cannot count the sheer number of times I would have a significantly higher ability to work and produce if I simply did not have to sleep, and I have attempted to go entirely without sleep multiple times.

I refuse to rest on the Sabbath day whatsoever, and it is one of the only things God or the Bible taught that I have zero issue with blatantly disregarding entirely.

God may have rested on the Seventh Day, but I sure as shit will not.

Not only that, but we can only last around 2 weeks without sleep before we straight up just fucking die.

If God has made any mistakes, sleep is one of them, and there will never be a single day where I do not hate sleep with every ounce of vitriol my tiny fuckin heart can muster.
