All of the potentially habitable planets found in their survey are around K stars, which are cooler and slightly smaller than the sun, Petigura said. But the teams analysis shows that the result for K stars can be extrapolated to G stars like the sun.

If the stars in the Kepler field are representative of stars in the solar neighborhood, then the nearest (Earth-size) planet is expected to orbit a star that is less than 12 light-years from Earth and can be seen by the unaided eye. Future instrumentation to image and take spectra of these Earths need only observe a few dozen nearby stars to detect a sample of Earth-size planets residing in the habitable zones of their host stars.
For NASA, this number that every fifth star has a planet somewhat like Earth is really important, because successor missions to Kepler will try to take an actual picture of a planet, and the size of the telescope they have to build depends on how close the nearest Earth-size planets are, said Andrew Howard, astronomer with the Institute for Astronomy at the University of Hawaii. An abundance of planets orbiting nearby stars simplifies such follow-up missions.

I knew I could depend on you.
“If life is bacterium then Id be surprised if there wasnt a lot of it out there in the galaxy.”
I’d be very surprised if we find even bacterium anywhere out there. We still know of no way that life can spontaneously appear from inanimate matter, so why would we expect to find it anywhere we look?
I think I've met him. Exeter Sanford, I believe.
“and well likely never visit a single one.”
The Voyager space craft launched in the 70’s have just recently left our solar system. If they had been sent on an intercept of Alpha Centauri, the next closest star, they would arrive in just less than 100K years.
We may not know how, but we can be certain that.
“We may not know how, but we can be certain that.”
No, we can’t, but many will keep telling themselves that because they don’t want to accept the ramifications of the alternative.
Reality has to arrive somehow.
Let me know when it does for you.
Even if we assume that life requires a literal act of God, we cannot assume that earth is the only place He deigned to act.

LOL!
“Even if we assume that life requires a literal act of God, we cannot assume that earth is the only place He deigned to act.”
I agree. If he only intended for us to be here on earth, why bother with the rest of His infinite creation? He either made us the only ones, and intended for us to someday go out and subdue other worlds, or He made life on other worlds, too. Maybe both. I know He created life here, but I learned long ago to not assume I know all of His plans for His creation.

I wouldn’t call that an assumption, I’d call it the most reasonable conclusion from the evidence we have available.
*shrug* There’s more Biblical evidence for extraterrestrial life than there is for the western hemisphere.
Maybe if you try to read that into the text.
People come from the heavens above, find earth girls attractive, mate with them and have children with them.
It’s right there in Genesis.
Show me any mention of the Americas.
