Ancient civilization - visitations, misunderstood technology.
Ancient civilizations were complex societies that developed in river valleys and fertile regions, characterized by cities, organized government, specialized labor, and monumental architecture, with major examples including Mesopotamia, Egypt, Indus Valley, China, Greece, Rome, Maya, and Inca, each leaving lasting legacies in law, philosophy. They arose thousands of years ago from primitive Stone Age hunter/gatherer societies seemingly overnight in archaeological time. It would seem they had help and guidance from someone with superior knowledge. Aliens? Maybe. It would be extremely arrogant to think out of the billions of galaxies in the observable universe, and the billions of solar systems in each of the galaxies, and all the planets in each of the solar system, that we (humans) are the only intelligent species. And the universe is billions of years old. So yes, there are aliens out there, and they are probably more advanced than us. We are about one million years old, and have gone from hunter/gatherer to space travelers in that time. And Earth is several billion years old. It is not impossible that intelligent species have evolved during those billions of years, and risen to our current intelligent level, if not higher, then got wiped out by ancient apocalyptic events as recorded by the archeological record by researchers like Abraham Hancock, who has spent decades researching ancient apocalypses like the great flood. That one event appears on every continent by every ancient civilization, documented on stone, clay, papayrus scrolls, paintings, on cave walls. As well as origin mythology stories. They are all the same. The gods came from the sky, the stars, in flying ships. But our ancestors didn’t know what they were seeing, and described them in language they had, flying carpets, flying chariots, swallowed by giant fish (whales) like Jonah in the Bible. Sounds like he was taken by a submarine) God talking to them in a burning bush. Angels. These are just some examples. These encounters are documented in ancient texts like the Bible, ( so many examples, like genesis, book of Enoch)Sumerian clay tablets, Hindu texts, Mayan texts. Even oral stories handed down generation after generation, by African tribes and Native American tribes in the south west, who didn’t have a written language to document the stories.
