@Vezon Actually, considering the chances. Assuming in our galaxy (the milky way) there are morethan 6,000,000,000 stars (just checked wiki - it is estimated 300 billion stars), and assuming each of them having their own solar system and there may be a likelihood hood that they have "goldilocks" condiitons. Such stars I can think of off the top of my head are gliese 581 specifically refering to the 4th planet "gliese 581d". Such planets are thought to host life. Now assuming there might be many many many galaxies each with billions of stars. The chance of a hospitable planet is quite likely. The number of planets being able to support life seem all that more likely.
