All that we can see with our naked eyes when we look towards the sky in the night are the stars. But, can’t there be any more survivors in the universe other than us? What I presume is yes there can be survivors. We are just a small part of the Milky Way and our only star being the SUN. There are around 30 billion stars in the Milky Way only and atleast 16 billion planetary systems. Isn’t it possible for more beings to be living around our earth?

We expect that the living organisms can’t live in the radioactive zone; but there are some bacteria that have adapted themselves and live by the lining of the radioactive reactors. Similarly, there are beings which do not need oxygen to survive; even a slightest amount of oxygen finishes their existence.

But, we are all a small part of all this. This universe is huge with lots of hidden truth..

Please add something to this, if you know more about extraterrestrial life.
