The universe is ridiculously large. To think that whole galaxies are moving away from us faster than the speed of light is almost incrompehensible (ie if you could travel at that speed you would still never catch up, even if you had 45 billion years to try). Insane. One thing I am pretty sure about though is that there definitely is some kind of other life form out there. Whether we will ever see or find it I'm not sure and probably not. The distances are just too vast.
There are even theories that outside of the universe there are other unverses or that the universe is one big bubble which expands and then collapses back to a point of singularity.
Crazy shit.
