Big Bang!

This is called the Hubble Ultra Deep Field. Starting in late 2003, astronomers pointed Hubble at a tiny, relatively empty part of our sky (only a few stars from the Milky Way visible), and created an exposure nearly 12 days long over a four-month period. The result is this amazing image, looking back through time at thousands of galaxies that range from 1 to 13 billion light-years away from Earth. Some 10,000 galaxies were observed in this tiny patch of sky (a tenth the size of the full moon) - each galaxy a home to billions of stars. -- Source

Looking at that picture brings in a perspective on how little we really are.

So, why not swing for the fences in the little time that we are here, because in a few years, nobody is going to care, whether we failed or not.
