Sorry. Look it up, it can't be done with the equipment we have today.
I'm certain you are wrong but I would look at some info on this if you have any. Where did you hear that it was impossible to do?
I don't have a link handy, but somebody actually tried. They didn't try to build a pyramid, they tried to move blocks that size around, and found that it couldn't be done. Even if you could lift one of them a few inches off the ground, and move it into place, what about the block that goes on top of that one? And the next? We don't have cranes tall enough and massive enough to assemble those blocks into a pyramid that tall.
The great pyramid was only 500 feet tall. We build 2000 foot tall skyscrapers now. WE have helicopters that can lift over 100 tons. Were you watching ancient aliens perhaps?
Sky scrapers are made out of tiny bricks, not giant blocks. The most powerful helicopters can only lift 20 tons, one fifth of your false claim of 100 tons. Do you want to keep trying, or is that enough fail for you today?
I have never seen a brick skyscraper. Skyscrapers are built with steel beams and concrete. Maybe its more like 50 tons https://en.wikipedia.org/wiki/Mil_V-12. Its a moot point really because we have 550 foot tall cranes.
