Question

how did life begin? the answer should not depend on any religion so i don't want any conflicts just because of the question or answer.....

Answer 1

well it's a very interesting question..
but even Scientists do not know how life began on Earth. They do know that the early Earth’s atmosphere was very different from the atmosphere now.

In 1952, Stanley Miller was working with Harold C. Urey designed an experiment to see how complex organic molecules might have formed under the conditions of early Earth. They believed the early Earth atmosphere would have been composed of methane, ammonia, hydrogen and water vapor. They sealed these gases in an airtight container, and then exposed the gases to sparks of electricity to simulate lightning. They continued the lightning for a week, and by the end, a reddish-brown substance had coated the walls of the container. This substance contained 11 of the 20 amino acidsused by life on earth. Since Miller and Urey performed this experiment, its results have been confirmed many times by other scientists. Many scientists now believe that the early Earth’s atmosphere was composed of carbon dioxide, nitrogen and water vapor.

Modern experiments with this mixture of gases produce similar results suggesting that early conditions on Earth produced complex organic molecules that probably became the basis for the development of more complex organisms. However, scientists have not been able to replicate the formation of even simple organisms, or anything that can really replicate itself. There are several theories as to how the amino acids might have made the leap into the complex, self-replicating life we see today.

Answer 2

Our life originate from inorganic and organic matters, because of lightening the sea inorganic matter changes into organic or Then there is a generation of Carbohydrates, protein ,fats after that RNA and DNA .Then From these Genetic material cell originate and Life originate.
