Massive, Old Terrestrial Planets = More Likely Life

The more surface area a terrestrial planet has, the more likely it will harbor life - because it has more reaction area and volume to do it, not to mention more gravity to pull in material (especially from organics-heavy comets). And Kepler 10c is 10 billion years old too, so it's had more time to do it. Even if the recently discovered mega-Earth Kepler 10c is a toasty 5700 Kelvin, there will be others that are not.

We should be looking at large, old terrestrial planets for evidence of life.
