life outside of what I know

I watch a show last night on fish/animal life in the deep black oceans. How life can be into being without any light and deal with the pressure of the water. When we as humans go and explore this unknown world. As a child, I always looked at books that had unseen animals and fish in them. They looked they just stepped out of a cartoon or as fairy tale. To this day, I couldnt tell you what was true or false.

What life is out in space? How do we know as humans what is life or what is not? Theres a force of engry... it wouldnt have life? It's not real? What or who puts a label on it to say "yes this is real" "no this is just a chem thing"

Anyways, I am getting too deep for me to be at work. Damn Gene has a big bag of peanut M&Ms. Only have a big ONE handfull.
