Collins says belief is ultimately a matter of faith—that God's existence can't, in the end, be proved by science. And yet he sees plenty of "pointers to God," natural phenomena that imply the existence of a biblical God. Here are Collins's "pointers":
- There is something instead of nothing.
- The unreasonable effectiveness of mathematics, which make simple and beautiful laws.
- The Big Bang: out of nothingness, the universe came into being. That cries out for explanation, since we have not observed nature to create itself . . . it causes us to postulate a creator, and the creator must be outside of time or you haven't solved the problem.
- The precise tuning of the physical constants in the universe. If gravity was a little weaker, things would all start flying a part. You can see a creator in these constants. Francis Collins
