How did dinosaurs form?

How dinosaurs were born is still inconclusive.

At present, it is believed that the earliest organisms were born in the ocean by thunder synthesis. They only had one cell, and then the genes mutated, resulting in more gene types, and then the fittest were eliminated and the unsuitable ones were eliminated. In order to catch prey, Allosaurus lifted its body through its forelimbs, so that its tail acted as a balancer. The whole body takes the belt as the hub and develops into a dinosaur with a special reptile form.
