What evidence do we have for the origin of life from inanimate matter?

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed in the Big Bang theory, when gravity pulled swirling gas and dust in to become the third planet from the Sun.

Like other terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

No trace of life was present during that time period. Due to environmental changes, primitive organisms such as unicellular organisms were created on the Earth. Thus, it was said that life was created from inanimate matter on our planet.


The theory of abiogenesis says that life has come from things that were not alive. The Miller-Urey experiment (1953) and other similar studies and experiments have shown that the different chemical parts used by living organisms are all made from nonliving or inorganic matter.


In the experiment, an atmosphere with ammonia, methane, and hydrogen sulfide but no oxygen was made over a bed of water. This was made to look like the atmosphere on early Earth. At the end of a week, compounds like amino acids that are easier to make were made. Proteins in living things are made up of amino acids. So, we can assume that life came from something that was not alive.
