Death and Eternal Life
There is no soul, and there is no judgement after death.
Our atoms are eternal; they existed before us and will continue after us.
The purpose of all living things is the perpetuation of their DNA. DNA is what we are.
Humans carry a second inheritance: our ideas, knowledge and theories. Like DNA, they can live beyond our lifetime, and the best ideas and knowledge can live forever.
We stay alive for as long as our descendants and our ideas stay alive. This is how we obtain eternal life.
Death follows the universe's rules. We do not fear it.
