within the next 20 years are very good.
Which is why I said Quote (DoctorOfSpace)
I suspect we won't find an Earth like planet for some time
Quote (HarbingerDawn)
even the collision event that formed the Moon is now known to be a not-so-uncommon event in other forming systems.
Has to hit pretty specifically. I'm not saying it is out of the question just seems rare, but I guess on universal, and even galactic, terms rare is common enough.

I see no reason why the Earth's formation should be regarded as exceptional.
I'm sure plenty of rocky worlds will be found. I meant in regards to finding one like Earth in regards to the atmospheric composition and size. Basically a second Earth, even one larger would be a lucky find. Our atmosphere is the way it is because life exists, so if we find a planet with similar composition then that is a flag for life which is what I meant when I doubt we will find one for some time.
