Here's another type of creationism that I thought I'd share with you from my research.
Gap Creationists: There is much more variability among adherents of this group than among young-earth creationists. Many members of this group accept that science has proven the earth to be very old, but they still generally want to interpret the Bible literally. The result is the concept of the “gap.” Essentially, gap believers think there has been both a creation and a “recreation,” and that the period between these two is not recorded in the Bible and could be very long. Humans appeared only in the “recreation.” There is debate about exactly when the “gap” occurs in the Bible, but it is definitely before the “fall of man,” meaning when Adam and Eve were cast out of the Garden of Eden. Gap creationism is one type of “old-earth” creationism.
