How did ancient egyptians manage to build pyramids?aliens??
No proof that aliens built the Great Pyramid till now. But suggesting that ancient Egyptians built it especially with the technology we credit them with is no good either. There is absolutely no evidence that pyramids were used as tombs. No mummy has ever been found in any of them. The practise was to bury the Pharaoh in Mastabas and in later times in the Valley of the Kings. Regarding who built the 3 pyramids of Giza, the cartouche inside the Great pyramid is a subject of some debate regarding its authenticity and whether its actually spells Khufu. Other than that no inscription inside the 3 pyramids of Giza has been found. People usually take note of various inscriptions in the auxiliary structures surrounding the pyramids and then use them to attribute a pyramid to a Pharaoh. Similar is the case with the Sphinx. Regarding construction, the Great pyramid is made up of approx. 2,300,000 blocks weighing 2.5-50 tons. That’s putting them at a rate of 1 block every 3 minutes to complete i
