A series of unproven theories as a basis for a new theory that further unproven theories can be based on. The cornerstone of modern science. There really needs to be more documented, observable data before there can be any remotely credible theory about how abundant or desolate our universe is of life. Using such observable data (we know the name) we could only surmise that in 100% of solar systems with a similar sun, bearing a planet at an adequate distance from it's sun, will not only support life, but would have life. Common sense[?] would dictate that's very unlikely, but there's no scientific basis yet to even theorize otherwise until we can find a way to get that data. To come up with absolutes about planets such distances away is foolish given we don't know half a shit about the planets right next to us.
