This can be demonstrated with help of Miller and Urey experiment:

They took a blend of alkali, hydrogen sulphide and methane and water and gave it a temperature of just underneath 100 degree Celsius and presented it to 25000 V electric sparkles to take after the lightning. Following 8-10 days 15% of carbon from methane had been changed over into organic compounds such as carbohydrates, proteins, fatty acids etc. which could react to form complex compounds. So fundamentally life originated from lifeless issue.
