All very interesting but given the enormous distances of light years separating us and the laws of physics, they if they exist can never visit us and we can never visit them. However for the last forty years earth has been transmitting enormous amounts of digital data. Perhaps someday a return message may be received.

I dunno. I suspect there are a lot more than that. Do we really have to find every single blade of grass on our planet before we are willing to say the planet is pretty much covered in the stuff?
Kepler was really quite amazing for a severely shortened mission. It only looked at one tiny spot in the sky and discovered so many planets and potential planets. Even more amazing when you realize that it could only spot transiting planets meaning it missed those on a right angle orbital plane or too far out from the star to have passed while we looked.
If a planet were the same distance from its star as earth is from the sun it only transits for a few hours once per 365 days.
715 new planets and still nothing to watch on any their tv stations.
