1. How did the life come on earth explain in brief ?
-----------------------------------------------------------------------------------------------
ans- see nobody knows exactly how life came to earth. when big bang was crashed then earth was created, but actually it was made from dust, air and other materials. slowly and steadily water came, due to changes in the environment, atmosphere was created
and animals started taking birth. then after decades monkeys evolved to humans and today you can see how much scientific power has increased.
thus,we can conclude that life occurred due to environmental changes.

Answer:
Explanation:
Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one weird form or another.
Indeed, some scientists think life appeared the moment our planet's environment was stable enough to support it.
The earliest evidence for life on Earth comes from fossilized mats of cyanobacteria called stromatolites in Greenland that are about 3.7 billion years old. Ancient as their origins are, these bacteria (which are still around today) are already biologically complex—they have cell walls protecting their protein-producing DNA, so scientists think life must have begun much earlier. In fact, there are hints of life in even more primeval rocks: 4.1-billion-year-old zircons from Western Australia contain high amounts of a form of carbon typically used in biological processes.
