Earth is home to millions of species of living things, including humans. It is the only place known to have life in the universe. The earth was formed about 4.54 billion years ago, and life appeared on its surface in the last billion years. Since then, the Earth’s biosphere has changed the atmosphere and abiotic conditions on the planet, allowing the proliferation of organisms that live only in the presence of oxygen and the formation of the ozone layer, which works with the Earth’s magnetic field to block harmful radiation, allowing life to exist on the surface. the earth. The ozone layer blocks ultraviolet rays, and the earth’s magnetic field displaces and pushes away charged elementary particles coming from the sun at great speeds and pushes them away in outer space away from the earth, so they do not cause harm to living organisms.
The physical characteristics of the earth and the appropriate astronomical orbit in which it revolves around the sun, as it provides it with warmth, energy and the presence of water, led to the emergence of life and the continuation of life on it until the present era. , Where scientists believe that the sun will rise in temperature in the future and expand and grow until it becomes a red giant and its diameter reaches the planet Venus or even the Earth’s orbit, as they see the development of stars similar to the sun in the universe when the star’s life is close to the end and its hydrogen fuel runs out. Then the high temperature of the sun ends life on Earth. This is if another cosmic event did not happen to it before that – such as the explosion of a nearby star in the form of a supernova – that would end life on it.

More than 7.7 billion people live on earth, and the various resources of the earth maintain a huge global population of people, who divide the world among themselves and are distributed over about 200 independent countries, and humans have developed diverse societies, civilizations and cultures, and interact with each other in a variety of ways that include diplomatic communication, tourism trade and military combat as well. Different theories and representations of the earth appeared in human culture. Some ancient civilizations embodied it as a god, some believed it to be flat, and others said it was the center of the universe. The current belief states that this planet is an integrated environment that requires human supervision over it to protect it from the dangers that threaten it, which are Ultimately, it will endanger the person himself.
