Dinosaurs are prehistoric animals that appeared on Earth as early as 220 million years ago. They range from the smallest, Compsognathus, to the largest, the fragile Dicavelosaurus. they are diverse and have complex habits. There are docile herbivores, fierce carnivores, and omnivorous dinosaurs.
They were originally dominant at the top of the earth's food chain, dominating land and sea, and survived for a long time on earth. They disappeared from the planet until they suddenly became extinct 65 million years ago. From then on, mammals began to rise until the count. Millions of years ago, humans were born and created a glorious civilization.
Why dinosaurs, which ruled the earth for more than 100 million years, did not give birth to civilization? And only a few million years of human history but the birth of civilization? The reason is actually very simple. The emergence of civilization was formed by two reasons: external conditions and the evolution of the organism itself.
The first reason is that in prehistoric times, when dinosaurs lived in external conditions, the climate was warm and food was abundant. Under such conditions, dinosaurs did not need much intelligence to survive. Instead, to prevent predators and promote predation , both herbivorous and carnivorous dinosaurs evolved toward larger body sizes. They had many defects, and their brains were not sufficiently complex. Therefore, in the course of biological evolution, they will gradually be eliminated from the earth.
The more complex the external conditions are, the higher the level of biological evolution will be. If there is sufficient food and a warm climate, there is no need for further adaptation to the environment, and there is less incentive to evolve. The second reason, then, is the evolution of the organism itself. There is a good saying that the nature of evolution is piles of wood, and the nature of civilization relies on a complex brain with the ability to think logically.

To survive, we must find ways to improve our intelligence. We must have excellent predatory skills and the ability to avoid wild animals. Starting with apes, humans have evolved and grown under complex external conditions.
After humans evolved to Australopithecines, who could walk upright, their intelligence had surpassed that of reptiles, birds and other mammals. They could use tools. Later, Homo sapiens would have greater brain capacity and more tools to make and carve rock walls for painting.
By this time, quantitative changes caused qualitative changes. The spark of civilization began to blossom. All this was not done overnight, but as a matter of course. After an evolutionary period longer than that of the dinosaurs, a civilization shaped by humans would be born under the influence of many factors.
