Why do scientists differ on the origin of man?

Man appeared several hundred thousand years ago. Its origin is still shrouded in mystery, since the process of separating it from the animal world took place too long ago. Scientists do not have accurate information about the origin of man. They draw conclusions based on the facts they receive. The generally accepted standard of human origin is Darwin’s theory. In his opinion, man descended from a monkey. This is proved by similar DNA and other biological indicators. Others disagree with his point of view. And they put forward different theories.
