And that's not even considering the possibility of life occur on planets that we wouldn't consider there even being a chance of it occurring (like say on a hot, arid, high gravity world for instance).
The possibilities are just staggering and mind-blowing.
Some people ask "Is there life out there?"
I ask "How can there NOT be life out there?"
To think that we are the sole inhabitants of a universe whose size is beyond our science to measure (and I dare say our comprehension), its idiotic, and just plain arrogant.
I have always wondered what phenomena makes it impossible to fit something back into a package after you just pulled it out.
Well I believe that but scientists sure don't! They gotta find the origin of everything.
The world is full of fear and despair, that is is why we must find the light in this pit of darkness.
