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

Explanation

The British Scientist J.B.S. Haldane suggested in 1929 that life must have originated from inanimate matter (lifiless matter) consisting of simple inorganic molecules such as methane, ammonia and hydrogen sulphide, etc., which were present on the earth soon after it was formed . The evidence for the origin of life from inanimate matter was provided by the experiments conducted by stanley L. Miller and Harold C. Urcy in 1953. They assembeld an apperatus to create an early earth atmosphere which was supposed to consist of gases like methane, ammonia and hydrogen sulphide, etc., (but no oxygen ), over water. This was maintained at a temperature just below `100^(@)` C and electric sparks were then passed through the mixture of gases (ot simulate lightning ) for about one week. At the end of one week, it was found that about 15 per cent of make up protein molecules found in living organisms. This experiment provides the evidence that the life originated from inanimate matter (or lifeless matter) like inorganic molecules.
