The size of everything

I have stumbled upon a very nicely done flash animation visualizing The Scale of the Universe. It makes one feel so small and unimportant. The more I think about it the more our existence on this remarkable creation baffles me and raises questions that might never be answered.
Moments like these reminds me that those 100 years given to us is nothing compared to the size and number of possibilities and mysteries waiting for us to be explored. That is why we have to live every day admiring the beauty and complexity of Everything. That is why we have to live right here right now!
