Kepler 444's Known Planets Probably Can't Harbor Life.

To put it briefly, the habitability of a planet depends on it's distance from its star, the composition of its atmosphere, and the type of star its orbiting. If our own solar system is at all typical then planets like those known around Kepler 444 and reported in the paper arXiv:1501.06227 do not have atmosphere or have a Venus like atmosphere.
If there is another Earth size planet to be found, father out, where it's a bit cooler it could be a home for life. If it did have life that life could, due to the age of the planet, have been in existence long before life on Earth.
Kepler has taught us, and continues to teach us just how many solar systems there are, and how long planetary systems with rocky planets could have existed. This gives life more time to develop intelligence.
