What a vast amazing place we live in! As a species, modern humans appeared on Earth about 300,000 years ago. Our dexterity and high-level brain capability enabled us to thrive and develop our "modern" society.

Evolution previously led to different life forms on this planet. This variation could also apply to other planets with very different results. However, our self awareness and ego create a tendency for us to define the entire universe with human-like characteristics--anthropomorphism.

When life evolved into complex organisms which reproduce the way we do, the specialization meant we must age and die. I personally honor this destiny by welcoming death without an afterlife. 

While we cannot exist forever as individuals, we can pass some DNA to the next generation. However, the desire for eternal life makes many of us wish for something more and creates a business opportunity.
