Watch the movie The Truman show. His world has a dome on top, or the show under the dome. Use AI to explain it to you. It's basic research. Yes humans are controlled using the banking system. We are enslaved by the banking system. The sun and moon are inside the dome and are just as lightbulbs.

The stars and planets are decorations embedded inside the dome. You can't leave the dome so going to a planet is propaganda.

I don't know about the pyramids or what their function was, it's not really part of the flat earth theory but i suspect during that time they knew the earth was flat and a dome above us, so they just of used that physics to build them. Aliens didn't build the pyramids, that's a lie. Aliens don't exist.
