A God of the gaps argument is one that argues that since some phenomenon is unexplained, it must be due to God.
- "Scientists can't explain how life came to be. There must have been a god to create the first life form."
- "The Big Bang theory doesn't explain what caused the Big Bang. There must have been a god to set the universe in motion."
- "The bacterial flagellum is too complex to have evolved through natural means. Therefore, an intelligent designer must have been involved in its formation."
A god of the gaps argument is an argument from ignorance: it boils down to "We do not know how X happened, therefore X was caused by a god. However, ignorance is never an argument for something. It merely means we do not (yet) know the cause of the phenomenon.
To see why this argument is a fallacy, we can consider similar arguments could have been made at different points in human history:
- 2000 years ago: "We do not know what causes lightning, therefore it must be the god Thor throwing lightning bolts from the sky."
- 1500 years ago: "We do not know what causes diseases, therefore they must be punishments from God (and thus prove God's existence)."
- 500 years ago: "We do not know what keeps the planets in their courses. There must be angels pushing them along."
- 200 years ago: "We do not know how the many species of plants and animals could have appered, therefore God must have created them."
- 100 years ago: "We do not know how the universe started, therefore God must have done it."
- 60 years ago: "We do not know how genes are passed from parent to child, therefore traits must be imprinted upon the soul."
As new explanations emerge, the gaps in our knowledge shrink, leaving less and less room in which to fit a god. Since human knowledge keeps growing all the time, it does not seem like a safe bet to assume that any given gap will remain one for very long.
