re: Ancient civilizations. Y or N?

The monoliths in Peru pretty much solidified it with me. The huge rocks weighing thousands of tons seamlessly fit together are an engineering wonder. It's called "cyclopian architecture". The antedeluvian ancient world is a rabbit hole you can disappear down. All cultures have oral traditions of a great flood and giants. The island of Sardinia off the coast of Italy has thousands of burial mounds where giants were buried. I believe the giants were offspring of the Watchers written in about in Enoch 1. Enoch 1 expounds on Genesis 6:4. The Watchers brought advanced technology with them and taught man "forbidden" knowledge. There are several researchers who know a lot about the subject. One is Timothy Alberino amd another is LA Marzuli.
