Looking for God—or Heaven—by exploring space is like reading or seeing all Shakespeare’s plays in the hope that you will find Shakespeare as one of the characters or Stratford as one of the places. Shakespeare is in one sense present in the same way as Falstaff or Lady Macbeth. Nor is he diffused through the play like a gas.
If there were an idiot who thought plays existed on their own, without an author . . . our belief in Shakespeare would not be much affected by his saying, quite truly, that he had studied all the plays and never found Shakespeare in them. . . .
I am not suggesting at all that the existence of God is as easily established as the existence of Shakespeare. My point is that, if God does exist, He is related to the universe more as an author is related to a play than as one object in the universe is related to another . . .
To some, God is discoverable everywhere; to others, nowhere. Those who do not find Him on earth are unlikely to find Him in space. (Hang it all, we’re in space already; every year we go a huge circular tour in space.) But send a saint up in a spaceship and he’ll find God in space as he found God on earth. Much depends on the seeing eye.
–C. S. Lewis,
God is not discoverable or demonstrable by purely scientific means, unfortunately for the scientifically minded. But that really proves nothing. It simply means that the wrong instruments are being used for the job.
