Did the knowledge we had back in the days of building pyramids, mathematics, chemistry, medicine,, hieroglyphs, biology, physics, astronomy etc,etc been forgotten, lost, blocked or erased?. Why did it not progress up to today? Why is there such a wide gap in knowledge that we're just now starting to catch up (slowly) with ancient knowledge? Was it an accident or deliberate and if it was deliberate, who or what caused it? 👀
