Question

Are we alone in the universe?

Answer 1

A good question posed indeed!!!

This is the question which has put the complete mankind in confusion for many decades or maybe centuries.

Most of the space research centres are working out on this question.

They are sending satellites, rovers, etc. to different planets in the universe to find out of there are any other life forms present apart from the Earth's.

According to my opinion, I think there is life on other planets.

But until proven the presence of other life forms continues to just be a myth.

HOPE THIS HELPED YOU..
  

Answer 2

It does not seem so...

Scientists are finding new facts about the Universe each day. It is possible that there is another planet in the Solar system or our galaxy or some nearby galaxy.

Scientists are working out and trying to see if there is a planet that could have life.. some form of life..  there are as many possibilities of life existing  on another planet as there are not.

As life evolved on Earth over millions of years, it is possible that some form of life (which has growth, subsistence, death, recycling..) has evolved over millions of years on another planet. That form of life would be suitable for that temperature and pressure.

Perhaps we are not alone in the Universe. However the answer could only be obtained in future.
