Can we live on Pluto yes or no?

Potential for Life The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like. Pluto’s interior is warmer, however, and some think there could even be an ocean deep inside.

How was Pluto destroyed?
