The Message from Venus

In our world history class at school, we learned that civilizations on Earth began around 3000 BC with the Egyptian, Mesopotamian, Indus and Yellow River civilizations.

However, people from other planets who visit the earth say that until about 10,000 years ago, the earth had a continent called Lemuria that stretched from the south to the north of the Pacific Ocean, and a continent called Atlantis that stretched from Europe to the Caucasus. However, the continent of Lemuria sank into the sea 10,508 years ago (going back from 1960), and the continent of Atlantis sank 10,200 years ago (same), and the civilization at that time disappeared. It tells us that the Egyptian civilization is a civilization left over from the Atlantis continent.

In addition, the people of other planets said that the human civilization on Earth has ruined many times in the past, and now it is the seventh civilization. And also they said that they had been observing Earth for over 75,000 years.

If so, civilizations on Earth have existed for far longer than is commonly thought, and have risen and fallen repeatedly until they reach the present day.

Why did human civilization on earth have to ruin six times so far?
