"God of the gaps" is a term used to describe observations of theological perspectives in which gaps in scientific knowledge are taken to be evidence or proof of God's existence. The term was invented by Christian theologians not to discredit theism but rather to point out the fallacy of relying on teleological arguments for God's existence. Some use the phrase to refer to a form of the argument from ignorance fallacy.
Teleological argument - teology -A teleology is an account of a given thing's purpose. For example, a teleological explanation of why forks have prongs is that this design helps humans eat certain foods; stabbing food to help humans eat is what forks are for. A purpose that is imposed by a human use, such as that of a fork, is called extrinsic.
