“To properly define life, we might need to find some aliens”

Just read an article on BBC by Josh Gabbatiss on the definition of life and it got me thinking. I truly believe we are very far from knowing everything there is to know. When someone asks me: “And how does that work?” I mean, it is awkward to tell people “well, we don’t know exactly”. It is difficult to acknowledge that those “top”, “badass” scientists don’t really know enough, but it is the hard truth.

Anyway, if there is something scientists do is to keep their minds open to new possibilities. With Astrobiology, this is even more important! We don’t know what we are looking for, we just want to know more about what’s out there!
