Question

It is believed that life first originated in sea. What is the basis of such a belief?

Answer 1

The life is believed to be originated in sea water (also known as earth's primordial soup) because sea water contained all the essential elements that were required for the origin of first life. Secondly, at the time of origin of life, ozone layer was not formed, so terrestrial origin of life was not feasible. Sea water provided a sort of protection for the primitive life originating in it against the ultraviolet rays of the sun.
