Life on Other Planets - Universe Today.
There is no scientific reason for assuming life on other planets—or even for insisting on the existence of any planets outside our solar system, let alone a planet so uniquely suited to sustaining life as is earth. Only sun, moon and stars are mentioned on the fourth day—no other planets like earth are mentioned.
Key element of life is carbon, water in liquid form and DNA formation. Any planet with these element has huge possibility of life. Basically we need to seek earth-like planets to find the life on those planets. Astronomers believes there are milli.
Until a couple of decades ago, the only planets we knew existed were the nine in our Solar System. In the last twenty-five years, we’ve lost one of the local ones (Pluto, now classified as a “minor planet”) and gained about three thousand candidate planets around other stars, dubbed exoplanets. The new field of exoplanetary science is perhaps the fastest growing subfield of.
In an infinite universe, most scientists agree, the odds of life existing on a planet besides Earth are pretty high. It is unlikely, however, that familiar life forms will be found on any planet.
The Kepler spacecraft has found planet pairs on very similar orbits, and if such a planet pairing occurred in the right place, then both planets could sustain life and even help each other along.

It has been centuries now since humankind looked up to the sky and wondered, is there any other life out there apart from our own? Ever since that question has been asked, it’s been a mystery and many scientists and astronomers have come out with many theories about what lies out there and what they look like, if any exist.
