Why does this question arise in the first place? Do we, as an insignificant organism, want to be important? If we study the well-accepted theory of evolution, humans seem to be a fluke of nature. That is one of the reasons many theists, despite the overwhelming evidence provided by evolution, cannot accept it.
Many people are looking for the significance of, and the reason why, we are here. The development of life through natural means seems impossible because of the enormous odds. The universe is so enormous and beyond our understanding, while time is counted in billions of years. Life defies the odds. We have won that lottery because we are here. Remember, no matter how large the odds in a lottery, one can win tomorrow.
When we consider the “purpose of life” question we must take into consideration the fact that more than 90 percent of the life forms that have ever existed have gone extinct. Humans will eventually go extinct as well, some predicting within a hundred years, others predicting another large meteorite, such as the one that wiped out the dinosaurs, will do the trick or when the sun goes nova. Thus, we are in a temporary situation but for what purpose?
So I would like you to revisit the question “What is the purpose of human life?” but, before you do, you must answer the question ”What was the purpose of the dinosaurs’ lives?” Think hard about it.
