Logical Fallacies: God of the Gaps


I’ve wanted to do a series on logical fallacies for quite awhile. In general, I am going to use young-Earth creationist (YEC) arguments because, well, they commit a lot of them, despite Jason Lisle’s recent series on the Answers in Genesis website about fallacious arguing.

What is “God of the Gaps?”

The “God of the Gaps” argument is really just what it sounds like: It is a way to fill a gap in our knowledge with God.

Young-Earth Creationist Astronomy Example

Probably the most prolific use of the God of the Gaps fallacy in YEC arguments is that of the universe’s “first cause.” The YEC claim goes as follows: “Something must have caused the Big Bang. Astronomers don’t know what that was. It was God.” Or, substitute for that last sentence, “Why couldn’t it have been God?”

The answer is simple — it could have been. But it also may not have been. We now know what causes lightning. Three thousand years ago, the ancient Greeks did not, and they created an elaborate pantheon of gods where the King of the Gods, Zeus, was the one who threw lightning bolts to earth after they were made by his son, the god Hephaestus. They literally stuck not one, but two gods into that gap. Now that we know what causes lightning, I don’t think I’ve met any modern religious person who still claims that it is caused by a god.

Similarly, Apollo was once thought to draw the sun across the sky each day, since the ancient Greeks could not explain naturally why the sun seemed to cross the sky every day, only to return back where it was for the next. Today, we know why – because Earth rotates on its axis. That gap in human knowledge is no longer there.

The same could happen for the origin of the universe. Right now, we don’t know what happened to originate it. Many Christians – if not people from most religions around the world – use the God of the Gaps to fill that void in our knowledge with a divine creation. But we may in the future know what natural means caused the Big Bang. We may not. Regardless, to jump to the conclusion that God did it and we cannot know the mind of god or find a natural cause is to invoke this logical fallacy.

God of the Gaps: The Science-Stopper

Scientists, rational thinkers, and skeptics will often argue that the God of the Gaps fallacy is a “science-stopper.” I have seen Intelligent Design proponents and YECers argue that it is not, though I remain fairly unconvinced by their arguments.

The reason that this fallacy is a science-stopper is that once you say “God Did It,” you don’t have to go any further. If Benjamin Franklin followed the Greek pantheon and believed that lightning was simply Zeus throwing things ’cause he was mad, then what impetus would he have had to find out its true nature?

Using God as an answer simply gives you a supernatural answer. It doesn’t cause you to look for a deeper, natural explanation, but leaves you satisfied that it is beyond our understanding ’cause God Did It.

The Shrinking Role of God

Philosophically, if I were a believer in the divine, I don’t think I would care to use this fallacy, and that’s because of the ever-shrinking role of God. Each time someone uses the fallacy – that God is used to explain something – and then we are able to explain it in a purely naturalistic method, then God’s role has suddenly diminished, shrinking away from that claim.

Final Thoughts

The God of the Gaps fallacy is usually a pretty easy one to spot.
