“That one big question of our origin unites us, not because we agree on the answer, but because we all agree on the importance of finding the answer. Throughout history, it has been the foremost question of people searching for understanding: What is the source from which everything else came? Or, to put it closer to home: What, or to whom, do we owe our existence? This has to be the starting point for people who take life seriously — scientists and non-scientists alike. We cannot rest without the answer because absolutely everything of importance is riding on it. To know where everything came from, is to know where we came from. And where we came from has everything to do with who we are. And who we are has everything to do with how we ought to live.” ~ Douglas Axe, Undeniable
