We do care about planets like the Earth because by now we understood that life as a chemical system really needs a smaller planet with water and with rocks and with a lot of complex chemistry to originate, to emerge, to survive.

We love our planet Earth. We should - it is our home, and there's no place like home. There can't ever be a better place than Earth.

It's feasible that we'll meet other sentient life forms and conduct commerce with them. We don't now have the technology to physically travel outside our solar system for such an exchange to take place, but we are like Columbus centuries ago, learning fast how to get somewhere few think possible.

When we discover New Earth - a planet we could call home - the question of the 'plurality of worlds' will come front and center, reminding us yet again that we are not the center of the universe.

Don't dress to kill, dress to survive.

To survive is to win.
