In this video, we explore the technologies of ancient civilizations that were lost over time.

We uncover the secrets of the Egyptian pyramids, which may have been much more than just tombs. We will explain alternative theories suggesting that these structures were astronomical observatories, centers of spiritual power, or even advanced power plants.

We will also investigate how great civilizations achieved their feats and why their knowledge faded away over time.
