Second, though there's a lot we don't know about how life arose on this planet, what we do know is that organic molecules form surprisingly rapidly and easily under conditions similar to those that prevailed early in the Earth's history. It doesn't seem unlikely that there are hundreds, maybe thousands, perhaps even millions of planets in our galaxy alone where life as we'd understand it arose.

Another big discovery that changes the whole picture is that you don't have to be anywhere near a "habitable zone" to have things like massive, stable salt water oceans that may outlive their parent stars by billions of years.
