how did you come to that conclusion?
A study in history.
Ancient historian, Joseph Flavius, clearly identifies Magog: "Magog founded the Magogians, thus named after him, but who were by the Greeks called Scythians."
Another reliable source comes from Herodotus, known as the "Father of History." Herodotus writes of the bizarre and savage practices of the descendents of Magog known as the Scythians.
The Scythians had no written language, so much of what is known about them has been derived from the many precious and exquisitely crafted artifacts found in their frozen tombs in Russia, Kazyktstan and the Eurasian plains. These precious items included weapons, jewelry and clothing, and were meant to follow the deceased into the afterlife. They can be viewed in Russian museums, well preserved from their long stay in the frozen tombs.
Magog, Meshech, and Tubal = Russia
Persia = Iran
Cush = Ethiopia
Put = Libya
Gomer = Turkey
Beth-togarmah = Turkey, Armenia, and the Turkish-speaking people of Asia Minor
Then read Ezek 38-39
