atomant, I am not sure if Evolution itself assures life on other planets but together with the knowledge that Nasa's Kepler and K2 missions ( Kepler Mission Planets In Habitable Zones ) have discovered, I would agree that Evolution would be part of that answer.
Besides the Earth, there are so far, 12 other known planets in the Universe that are located within 'the habitable zone' of other stars. Our sun is one of the key ingredients that allowed life to begin and evolve on this planet. It is therefore very viable that life exists on these other 12 planets as well.
