I am a scientist and a believer, and I find no conflict between those world views.
As the director of the Human Genome Project, I have led a consortium of scientists to read out the 3.1 billion letters of the human genome, our own DNA instruction book. As a believer, I see DNA, the information molecule of all living things, as God’s language, and the elegance and complexity of our own bodies and the rest of nature as a reflection of God’s plan.
I did not always embrace these perspectives. As a graduate student in physical chemistry in the 1970s, I was an atheist, finding no reason to postulate the existence of any truths outside of mathematics, physics and chemistry. But then I went to medical school, and encountered life and death issues at the bedsides of my patients. Challenged by one of those patients, who asked “What do you believe, doctor?”, I began searching for answers.
I had to admit that the science I loved so much was powerless to answer questions such as “What is the meaning of life?” “Why am I here?” “Why does mathematics work, anyway?” “If the universe had a beginning, who created it?” “Why are the physical constants in the universe so finely tuned to allow the possibility of complex life forms?” “Why do humans have a moral sense?” “What happens after we die?”
