The story of evolution

Primitive man came to Earth and did not know anything about any of its sciences, so he began to search for adaptation to the nature of his environment, and the first thing he searched for was safety from ferocious beasts, so his first industry was to make spears from tree branches in order to defend himself with them, and to use them in hunting as well. Then he started looking for something to help him cook food, and he discovered fire by rubbing stones together. The third thing was the clothing that protected him from the extreme cold and heat, and covered his private parts. It was made of animal skins.
Such is the creative nature of man, and that is why they say: Necessity is the mother of invention. With the development of time and its mechanisms, man has many things to use in life, using his developed mind, which competes with new ideas every day, until a time came when man expanded his thought and began to ask about everything around him.
