Details two people attempting to prove the existence of a gardener. One says there must be a gardener so they test it. The believer insists the gardener exists, despite the test showing that there is not one. The believer changes their story saying that the gardener must be invisible but the non believer questions this. It mirrors religion - often times we cannot prove God's existence but believers will continue to change the story until there is a narrative that fits their beliefs, even if it can't be proved
