Why are the Miller-Urey experiments essential to the theory of evolution? They showed that life can only come from life. They showed that electricity can create life. They showed how organic molecules could be made from Earth's early atmosphere. They showed the role that natural selection played in the evolution of modern day organisms.

They showed how organic molecules could be made from Earth's early atmosphere.

Explanation:

Miller-Urey experiments were based on the ides of a-bio-genesis. It means the production of life through the non biological factors. In this experiment it shows that life can be produced through chemicals and molecules that were found in the early form of earth and is composition.

It kind of gives off to the evolution theory and the amino acids which are the building blocks of life and were given rise to during the simulation.
