Ancient civilizations
It has always been impressive how so many civilizations have chosen the pyramid as a structure to build monuments. Many historians can’t decide what this shape represented for the builders or why it was chosen in different countries and in different time periods.
A new question to add is, why is there a pyramid on the moon? This is footage taken by NASA cameras on one of the craters of the moon. Yes, it doesn’t have the best quality, but what little we can understand from it is that there is a pyramid structure inside this crater.
