Thousands of years ago, in the latter half of the ice age, human crossed the Beringland bridge and entered Alaska from Asia. Their descendants explored along the west coast of North America. As early as 1000 BC, they covered almost all continents. It is unknown when the first group of people will arrive in the USA. Several archaeologists (scientists who studied past human bodies) believe that it is about 12000 BC. For thousands of years, American Indians have developed a wide range of languages, customs and civilizations as they travel across the continent. There are various tribal countries in the Americas, there are various countries in Europe, Asia, or Africa, many of which are diverse.
Neanderthal people are the main subspecies of early to mid-term glaciers, not the wild animals that are usually drawn, but very successful subspecies. They left Africa, moved to the edge of the glacial glacier, and survived under difficult circumstances. Their skills are sufficient to meet their requirements. The Neanderthales have explored and moved to the majority of the Earth that can reach on Earth for hundreds of thousands of years. According to DNA studies, they survived some of the end of the world's natural disasters in combination with glacial climate conditions, sometimes reducing the number to an estimated 25,000. In particular, it is estimated that the climatic impact of the super volcanic eruption of Duba 700 thousand years ago occurred deep in the cold climate of the Ice Age, human beings lost 10,000 people. Homo sapiens simply copied the Neanderthal people
Scientists judged that at least five major ice ages occurred in the history of the earth. These include Huronian, Cryogenian, Andean-Saharan, Karoo, Qauternary Ice Ages. Based on the geological evidence observed in the northern and northeastern part of Lake Huron (related to sediments in Michigan and Western Australia states), the Huronian ice age goes back to early Proterozoic Eon about 2.4-2.1 billion years ago I will. The low temperature ice age lasted from about 800 million to 630 million years ago, perhaps the most serious time in the history of the earth. It is believed that glacier ice sheets reached the equator during this period, resulting in the "snowball earth" scenario. This may be controversial (as mentioned above), as the sharp increase in volcanic activity is thought to have contributed to the greenhouse effect
