Many, many planets like this one have been discovered. They can't confirm the temperature or water presence exactly, as they work it out based on it's size, and distance from its sun. If its distance is just right, its in the 'Goldilocks zone'. Kepler 186 is a promising one. If there is intelligent life there, and they look at earth, they'd see dinosaurs. Scientists say that by day. the year 2015, they will have confirmed intelligent life, as they discover so many planets like this one all the time.

No, they will not see dinosaurs, they will see our society how it was 500 years ago.
