god dosent exist because humans originally evolved from simple organic molecules containing carbon. Energy from the sun, lightning, and earth's heat triggered chemical reactions to produce small organic molecules from substances present in the atmosphere. These molecules were organized by chance into complex organic molecules such as proteins, carbohydrates, and nucleic acids that are essential to life.
And proof of this comes from a famous experiment. two American scientists, Stanley Miller and Harold Urey, carried out an experiment in which they attempted to simulate early earth conditions according to evolutionists. They mixed water vapor with ammonia, methane, and hydrogen gases. They then sent an electric current that simulated lightning through the mixture. Then they cooled the mixture of gases, producing a liquid that simulated rain. After a week, they collected the liquid in a flask and analyzed the chemicals therein. They found that three amino acids (amino acids constitute the basic elements of proteins, which are the building blocks of living cells) were synthesized.
