I think you're using Occam's Razor incorrectly here. Here are all the facts: 1) There's an incomprehensibly large amount of stars and planets in the universe 2) On one of these planets (Earth), there are conditions which have lead to the appearance of life 3) These conditions are not unique to this planet We don't know of any fact that would exclude the possibility of life coming about on other planets with similar conditions, so using Occam's Razor actually tells us that there's probably lots of other life out there.
