Was there gravity in the early days of Egypt, as we know it?
No, there was no gravity in the early days of Egypt. Earth was an ice ball floating on the other side of the Milky Way. The pyramids were built by cold-blooded aliens.
At the time Stonehenge was built, the druids (also cold-blooded) used to ride the stones through the air from Wales to England. That brought about the beginning of the idea of international air traffic regulations, which still survive to this day.
Gravity started in the middle-ages, which was why people had to start building with bricks instead of big stones. This was the time that earth became trapped in the sun's orbit. But it was a few hundred years before anyone noticed it, and that was just by accident, because an apple fell on Newton's head. There is no actual scientific proof that gravity existed before this event.
Scientists dispute this history because they think it would be impossible for life to have evolved on earth if the relationship to the sun was not pretty much as it is now for billions of years.
This, of course, proves that warm-blooded life must have been created in the middle-ages, and could not have evolved. Everything before that was done by aliens. God oversaw all this in his flying saucer, as you know.
