Answer:

The settlement of America is the process of dispersal of the human species in the American continent. Scientific studies state that human beings are not originally from America, and it is clear that it was populated by humans from other places. Paleoanthropological and genetic evidence supports the hypothesis that the first settlers of America came from Siberia, the extreme northeast of Asia.

From the point of view of late settlement theory, Paleo-Americans entered the continent during the last ice age, when the passage to the New World through Beringia (the isthmus that is currently occupied by the Bering Strait) was possible. This happened between 15,000 and 14,000 years BC. On the other hand, the early settlement theory states that humans arrived in America much earlier, and is based on the discovery of remains whose carbon 14 dating is older than 14,000 BC. Some recent investigations take this date to about 33,000 years ago.1 To the paleoanthropological investigation is added the genetic information, which has served to reinforce some conjectures about the origin of the Americans. It is estimated that most of the American Indians are descendants of a group originating from Northeast or East Asia. The Na-Dené-speaking peoples are descendants of a second wave of migration that settled in North America, while the Eskimos arrived on the continent in a more recent migratory flow.2

After the Paleo-Americans entered the continent, the Beringia Pass was again covered by the sea, so that they were isolated by land from the rest of humanity. Except for the uninterrupted communication between Eskimos and Paleoeskimos from Alaska and Siberia and the case of a few brief Viking settlements in America, on the coast of Canada and Greenland, there is no conclusive evidence to support a transoceanic contact between pre-Columbian America and the rest of the world.

After the Columbian contact, various conjectures were raised to explain the origin of the American Indians, for example, resorting to the myth of Atlantis or the lost tribes of Israel. The advance of scientific research made it possible to demonstrate that there was no material relationship between the origin of the Amerindians and these beliefs, so these old hypotheses were discarded

Speculation about the nature of the Universe must go back to prehistoric times, which is why astronomy is often considered the oldest of sciences. Since antiquity, the sky has been used as a map, calendar and clock. The oldest astronomical records date from approximately 3000 BC and are due to the Chinese, Babylonians, Assyrians and Egyptians. At that time, stars were studied for practical purposes, such as measuring the passage of time (making calendars) to predict the best time for planting and harvesting, or with objectives more related to astrology, such as making predictions of the future, since, having no knowledge of the laws of nature (physics), they believed that the gods of the sky had the power of harvest, rain and even life.

Several centuries before Christ, the Chinese knew the length of the year and used a 365-day calendar. They left accurate notes of comets, meteors and meteorites since 700 BCE. Later, they also observed the stars that we now call new.

The Babylonians (Mesopotamia region, between the Euphrates and Tigres rivers, present-day Iraq, Hammurabi, Nebuchadnezzar and the Bible Tower of Babel), Assyrians and Egyptians also knew the length of the year since pre-Christian times. In other parts of the world, evidence of very old astronomical knowledge was left in the form of monuments, such as that of Newgrange, built in 3200 BC (on the winter solstice the sun illuminates the corridor and the central chamber) and Stonehenge, in England, which dates from 3000 to 1500 BC.

sergey [27]

Answer: Because of the connection between religions.

Explanation:

The mentioned religions are characterized by monotheism, and these are the three largest monotheistic religions in the world. When we talk about the mass acceptance of Islam in the Arab world, it is necessary to consider the holy book of Muslims, the Koran. The Qur'an states that the Torah (the holy book of the Jews) and the Bible (the holy book of the Christians) are also a divine work, but that they have undergone changes over time. On the other hand, the same god offered the Qur'an to the people, and the Qur'an itself states that it will remain unchanged.

Also, the emergence of Islam is related to the early Middle Ages, and the church did not send missionaries to Arabia on a larger scale, so people accepted Islam and rejected the ancient pagan beliefs. When we talk about the spread of Islam in Africa, it is a consequence of historical currents. Islam in Africa spread through Arab traders but also missionaries. People accepted Islam because of the dogmas that religion dictates; the teachings differed from what the previous religions offered. These are the main elements of the rapid popularization of Islam in these parts of the world.
