"Are Space Monsters imaginary creatures?" my son asks this morning, waking me at the usual 6a.m. Hmm... That's kind of an interesting one. You see, if you believe that a Universe as big as ours has probably spawned life on planets other than just Earth, then there are Space Creatures out there, somewhere, and no doubt by my son's criteria, they are indeed monsters. So, maybe the answer is no, Space Monsters are not imaginary, they're real.
But that kind of opens a whole can of worms, so to speak, that might be best avoided. And this entire line of logical reasoning calls into question other assumptions, such as, are dragons real? I mean, if you're going with the infinite-combinations-in-infinite-diversity argument, there just might be a dragon (or effectively the same thing) living on some planet out there, somewhere. Hmm. Maybe the best answer right now is to just close my eyes and go back to sleep... :)
