The Forbidden Book of Enoch“Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity” — Wernher Von Braun
Ivanov at Varna- lost city - grave found of early advanced civilization ~5000 BC. This was a very important archaeological find- predates most well known civilizations in Egypt, Mesopotamia, etc. Hidden civilization was found because they were digging to put in electrical wires! Entire civilizations can be taken out rather easily by nature it seems.
Eridu (present day Abu Shahrein, Iraq) is considered the oldest city in the world and, certainly, is among the most ancient of ruins. Founded in circa 5400 BCE, Eridu was thought to have been created by the gods and was home to the great water god Enki (who, later, would develop from a local god to merge with deities such as Anu and Enlil as Lord of the Universe, and was associated with Ea, god of wisdom).
