Actually I was listening to a podcast that explains this. They didn't have levers yet. They did have other devices but no lever.
you can't just not have levers.
It was before levers
Lol of course you can. They were invented at one point. And before that point... You didn't have them. I recommend: Let's Learn Everything episode 49: Goosebumps, (Not) Alien Pyramids, and Nessie & Cryptids.

I think the lever here is a stand-in for mechanical advantage. I don't believe anyone is seriously proposing they lifted the blocks with a very long stick.
But the length of the stick is what’s required for the lever, unless they used some kind of gearbox.
But others have levers
