history about earth

Earth's evolution process was as follows: - About 4.6 billion years ago, the Earth was born. At that time, the surface of the Earth was covered with magma and lava. The temperature was close to 5000 ° C. The remnants of the Big Bang kept hitting the surface of the Earth. - About 4.5 billion years ago, an asteroid named Theia hit Earth. The fragments formed the moon, and the tidal force of the moon slowed down the Earth's rotation. - About 4 billion years ago, a huge comet with water hit Earth. After that, Earth experienced a long-term rain that lasted for 3 million years. Earth became a blue planet, which laid the foundation for the birth of life. - 3.7 billion years ago, blue algae in the ocean began to photosynthesize, releasing large amounts of oxygen and growing explosively. - A billion years ago, Earth entered the Great Ice Age, which lasted for tens of millions of years. Earth became a huge ice ball. - About 500 million years ago, during the Cambrian-era, there was a great explosion of life, and all kinds of animals and plants began to be born. - About 200 million years ago, dinosaurs stepped onto the stage of history and ruled the earth for about 130 million years. - 65 million years ago, an asteroid with a diameter of about 10 kilometers hit the Earth, causing 90% of life to go extinct, including dinosaurs. - About 2 million years ago, the first Homo Spico was born on Earth. Humans gradually stepped onto the stage of Earth's history and ruled until now. During the Archean Era (2.4 billion years ago), the solid core was formed, the oceans were formed, life appeared, single-celled organisms appeared, and the Earth was occupied by the oceans. During this period, it also experienced the Huron Ice Age, where cyanacea produced oxygen under photosynthesis and large-scale biological extinction occurred. The second major cooling occurred when the Rodinia supercontinent was formed, and the sponge was the first animal to appear. After that, there was the Cambrian-era explosion of life in the Permian period, with the appearance of early vertebrae; the Ordovican-era extinction of land plants; the Sahara glacial period of early fish; the Devonian-era extinction of the carbonatite period of Pangu Continent; and the Caino-era after the extinction of dinosaurs, the ancestors of human beings appeared. At the beginning of the Earth's formation, it was one of the many new planets orbiting the sun. The original Earth was much smaller than it was now, and its surface was covered in magma. During this period, it was constantly hit by meteorites. Later, it was hit by a primitive planet the size of Mars. Its axis tilted 23° to form the four seasons, and the impact fragments formed the moon. Millions of years after the moon formed, the earth gradually cooled down and had a rocky and metallic crust. The moon also completed the cooling process. About 4 billion years ago, after the debris from the formation of the solar system hit the Earth, the Earth had oceans and an atmosphere slowly appeared. Life began to evolve from single-celled organisms to multicellularized organisms, from marine organisms to amputated organisms, terrestrial organisms, and sky organisms. After the extinction of dinosaurs, small mammals appeared on the stage, and humans multiplied and evolved on the African continent and went global.

In 1999, the American journalist David. Ike interviewed the knowledgeable South African wise man, Credo. Mutewa's interview was called the most shocking interview in the history of Earth. In the interview, Credo mentioned that in ancient times, the extraterrestrial lizardmen came to Earth as " gods ", modified human genes, transformed androgynous humans into men and women, taught humans language and knowledge, and even asked humans to mine. They would mate with human females to give birth to 'half-human, half-god' descendants to rule the human race. Credo also mentioned the appearance of the alien lizardmen, such as their height of more than three meters, slender figure, support of the body by the cartilages, different number of fingers on the hands, and some horns on the head. A lot of the information he said was related to ancient China mythology, such as the pronunciation of Nuwa and Pangu in Africa and the fact that they were believed to be lizardmen. The novel," The Couple's Universe: The Amazing Legend of Shen Zhen " is equally exciting. Everyone is welcome to click and read it!
