What are legitimate reasons to believe there may be life outside Earth's biosphere?

OK, I confess I am pretty conversant with this topic so I know all about the "all the stars", "size of the universe","we exist so they must", and Drake equation type arguments. I am hoping to find some truly original or deeply technical reasons why we might expect other biosystems to exist. Is there anything I have overlooked? Any thoughts?

When one of the meteors that was hit on earth some decades ago was tested it was guaranteed that similar processes that happened after Big Bang is happening is somewhere in the universe..this means the same processes may have happened in many other places too..so it is almost ascertain that existence planets similar to earth is possible...

Legitimate reasons are that there are actually microbials on other planets. Although small they may be able to develop into higher life forms although that would take billions of years. Longer than they would have before their planet was swallowed up by the sun as it goes into super nova D:

The presence of the manned space stations

People can make an answer but there is no a reason. (This is your so-called free will.)
God can make a reason but there is no an answer. (This is your so-called destiny & chance.)

Sometimes I say, newton's apple is more clever than newton.

Hope it helps.
