It's usually worthless trying to argue with tp4 though.
I'll just address the most common nonsense arguments by the conspiracy theorists:
The pyramids just does not make sense, It's far too complex to be a "just" a tomb.
It's just a pile of squared rocks put on top of each other. Tombs of maharadjahs in India are fare more complex with intricate marble details carved out of impressive sized blocks and over-the-top size. Some religious shrines (on all continents) are also quite crazy. So yeah more recent pyramids were relatively well made, but they had *centuries* of training at that point to perfect their building techniques. Earlier pyramids were really rough and not very far from cairns in concept. The Taj Mahal is just a tomb too, and is absolutely insane in size and execution.
So no, it's not "too complex" to be a tomb.
Even if you were a total boar's head of a human, spending that much resources to build something so useless as a tomb, out of all the possibilities at your command is unthinkable.
Insanely rich and powerful human builds some insane contraption in order to project his over inflated ego.. Yeah certainly unthinkable. Oh wait. Have you ever been outside and seen our modern cities with those billionaire owned sky scrapers ?
The ancient egyptian leaders, IF HUMAN, would've been among the only educated peoples,
Nope at their peak egyptians were generally quite well educated.
etc. etc. all these arguments go either in the "people in antiquity were way too idiotic to do any of that" or "these people were too intelligent to do any of that" two sentences apart. All of them missing the mark completely anyway, people are always the same.
