What if there are many universes, and only one in n universes develop intelligent life? One reason in favour of the multiverse is to explain why the laws of physics in our universe even supports the development of life to begin with. What if the conditions are so unlikely it only happens once or maybe twice for every n universes that can support life? Of course none of this can be proven, and arguably it's not even science, but I'm not entirely convinced by "the universe is so big, there has got to be other life out there!"-argument.
