inquiry hour 1.2 Are we alone in the universe?

This paragraph stuck out to me because i have always wondered if there was other life within space itself. We live on a planet, so how come there cant be other living organisms on another planet?

Hypothesis: If we are able to live and prosper on our planet, then there should be conditions on another planet somewhere to sustain living organisms and possibly aliens.
