Hey @moharkan, I am absolutely sure that there is a lot of life present in our universe. Although it is not really possible to have exact numbers about galaxies or the count of planets etc. the known / visible universe contains about 100 billion galaxies. The Milky Way f.e. includes billions of planets. So from a statistical point of view it is nearly impossible that no other planet exists on which life is possible.

An there is still another point:

Life as we know it is based on carbon, but nobody knows if life could take place under totally different conditions or not.

oo that's right i think personally we are still human being, we don't know in which other environment some other life can be possible, so for us it's hard to answer about can be other planet and life like we have .. thank you for your answer
