Answer 1

Hey

Here is your answer,

The evidence for the origin of life from inanimate matter , was provided through an experiment , conducted in 1953 , by Stanley L. Miller and Harold C. Urey . In experiment they assembled an atmosphere containing molecules like ammonia, methane and hydrogen sulphide , but no oxygen , over water. This was similar to atmosphere that thought to exist on early earth. This was maintained at a temperature just below 100°C and sparks were passed through the mixture of gases to stimulate lightning. At the end of the week, 15% of the carbon, from methane , had been converted to the simple compounds of carbon including amino acids which make up proteins and support the life in basic form. Thus, amply suggesting that life arose afresh on earth
