If you look up into the night sky at all the stars, you will only see about .0001 percent of all the stars in just our galaxy, the Milky Way. That is about 5,000 stars.

The Milky Way is just one of more than a hundred billion galaxies that can be seen using modern telescopes.

The nearest star to Earth, other than the sun, is Proxima Centauri (or Alpha Centauri C). This star is four light-years away. Our fastest spaceship would take ten thousand years to reach it.

The largest star, VY Canis Majoris, is over 5,000 light-years away. Its volume is a billion times that of our sun, and it would take over 650,000 years to walk a full circle on its surface.

Earth formed approximately 4.5 billion years ago. Human origins date back some 200,000 years. The whole of human existence accounts for a mere .004 percent on the world's time line.

Realizing the true insignificance we all hold in the entirety of the universe, it's really no wonder why people rely on religion to understand and give meaning to their lives.
