The simple assumption is this: with however many infinite galaxies and existences there are, ours simply cannot be the only one that houses life. Unfortunately, in our case, years and mileage spell the same sort of disappointing answer: if there is life out there, the chances of us crossing paths with them or even existing at the same time are impossibly slim.
