The end of the Glacial Era
Let us remember the interpretation of which the Atlantida existed in years 9000 to B.C.
(Glacial Era) or 900 B.C. (Age of Bronze). There are scientists who assure that happened in the Glacial Era.
In the glacial era, 20,000 years ago, the earth was in his majority covered with ice. For the years the 9000 B.C. the weather changes caused the defrost flooding great amount of mainland.
The investigators, who think that it was 9000 B.C. ago, consider that the Atlantida existed at the end of the glacial era, reason why its destruction was due to defrost of the planet, and then it was submerged under the water.
But if that had happened, even they would be left rest of the Atlantis under the water, and they haven't been found.
This theory is valid to be able to relate so many legend of the city that lived at heart of the sea.
In addition, 10,000 to B.C. had not been discovered metals and other materials like creating such strength.
The Age of Metals: chronology and periods
This age is the last stage of Prehistoric and it is divided in three periods, they have been marked by the use of three different metals:
The Brass Age: From the 5000 B.C. to the 1800 B.C.
The Bronze Age: From the 1800 B.C until the 800 B.C.
The Iron Age: From the 800 B.C. until the 100 B.C.
