The ancient Mayan built pyramids.
The construction time for a pyramid varied depending on its size and complexity, but the Great Pyramid of Giza, for example, is believed to have taken about 20 years to complete. Built during the Fourth Dynasty of the Old Kingdom of Egypt, it required a massive workforce and advanced engineering techniques. Other pyramids may have taken less or more time, but the 20-year estimate is commonly cited for large royal pyramids.
Yes, many did. The great pyramid and others that have survived, did so for a reason. Their shape made them more sturdy over time and were not the first design. Many steppe pyramids were built but were too steep and as the corners eroded, the whole pyramid fell under its own wieght. They were built too steep and did not have the base structure as seen in the great pyramid.
