If you look into pyramid building theories, you’ll see that is rather difficult to lift such heavy stones at such heights at such a speed. It’s likely they even used river-based hydraulic force. I’d say quite advanced compared to what else we see from 4k years ago. There’s many great resources and this topic (and many bogus ones), but for simplicity, I’ll link to Wikipedia here.

They virtually build themselves. Though whipping in the summer heat can be laborious.
