What is the "Gap Theory"Gap creationism (also known as ruin-restoration creationism, restoration creationism, or "The Gap Theory") is a form of old Earth creationism that posits that the six-day creation, as described in the Book of Genesis, involved literal 24-hour days (light being "day" and dark "night" as God specified), but that there was a gap of time between two distinct creations in the first and the second verses of Genesis, explaining many scientific observations, including the age of the Earth. It differs from day-age creationism, which posits that the 'days' of creation were much longer periods (of thousands or millions of years), and from young Earth creationism, which although it agrees concerning the six literal 24-hour days of creation, does not posit any gap of time. What is the "Day-age Theory" Day-age creationism, a type of old Earth creationism, is an interpretation of the creation accounts in Genesis. It holds that the six days referred to in the Genesis account of creation are not ordinary 24-hour days, but are much longer periods (of thousands or millions of years). The Genesis account is then reconciled with the age of the Earth. Proponents of the day-age theory can be found among both theistic evolutionists, who accept the scientific consensus on evolution, and progressive creationists, who reject it. The theories are said to be built on the understanding that the Hebrew word yom is used to refer to a time period, with a beginning and an end and not necessarily that of a 24-hour day.The differences between the young Earth interpretation of Genesis and modern scientific theories such as Big Bang, abiogenesis, and common descent are significant. The young Earth interpretation says that everything in the universe and on Earth was created in six 24-hour days, estimated to have occurred some 6,000 years ago. Modern scientific observations, however, put the age of the universe at 13.8 billion years and the Earth at 4.6 billion years, with various forms of life, including humans, being formed gradually over time.The day-age theory attempts to reconcile these views by believing that the creation "days" were not ordinary 24-hour days, but actually lasted for long periods of time (as day-age implies, the "days" each lasted an age). According to this view, the sequence and duration of the creation "days" may be paralleled to the scientific consensus for the age of the earth and the universe.Sources:Numbers, Ronald (November 30, 2006).
