This is very well done and it will definitely get you thinking about our place in the universe. I have no doubt there are civilizations galore out there. To me this is simple statistics. Seeing all of these galaxies out there is very humbling and I think it serves well as a step in the process of beginning to think outside the current paradigm. There is so very much we have yet to discover. What we do know is but a scratch on an all but infinite surface.
