So were there ancient civilizations?

There is ample evidence that ancient civilizations possessed high technologies and in their development were much ahead of our time. There is an opinion that some kind of global catastrophe destroyed ancient civilizations. And that they were in contact with representatives of other worlds that taught them technology, science and art.

Discussions on the topic so were the ancient civilizations, conducted by the students of the world for many years. Some claim that at one time on our planet there were several developed civilizations - Atlanteans, Lemurians, Hyperboreans and others. And they present the artifacts to the world. Others explain the origin of these artifacts as products of our civilization or counterfeits. Although there are a lot of artifacts, a group of researchers from Harvard University with computer modeling demonstrated how our planet will look after a global natural catastrophe or war that will destroy a person.

Taking into account all the factors influencing the external conditions for various materials, the scientists determined that in 50 years from the big cities there will be ruins, and in 10 thousand years - only gunpowder. All the artificial materials - concrete, iron, plastic - eventually completely decompose. About 2 million years on the planet there will not even be a hint that people lived here.

Similarly, this could have happened with ancient civilizations that disappeared from the face of the Earth several million years ago. They simply did not have any material artifacts left. True, such artifacts could have survived at Moon, where there is no atmosphere. So you can search there. And finally to answer the question whether there were ancient civilizations.

Here it would be appropriate to recall the scientific interpretation of what the ancient world is - a period in the history of mankind, distinguished between the prehistoric period and the beginning of the Middle Ages in Europe. In other regions, the time boundaries of antiquity may differ from European ones. For example, the end of the ancient period in China is sometimes considered the emergence of the empire of Qin, in India - the empire of Chol, and in America - the beginning of European colonization. Hence, one can imagine how little modern science knows if ancient civilizations were.
