There would come a day where every man wakes up and realises that he is no more than just a lone soul amongst billions of souls, on a planet in the middle of a solar system that is only one of millions of other systems in a galaxy placed in the vast ocean of endless balkiness of millions of other galaxies, surrounded by stars a million times bigger than the sun and some even bigger then a galaxy... and then you would think how surreal all of this is and you would wonder and you would be afraid of this notion.
It is pretty scary to be such a little thing in such a big place.
