Creation
"Creation" or "Creationism" is based on the revelation from God as found in the first part of the book of Genesis in the Christian Bible Old Testament. The creation is described as taking place over a six-day period, after which God rested. Strict creationists believe that these were 24-hour earth days and that the earth is quite young, while others calling themselves creationists take these to be "long periods of time" and typically believe the earth to be very old.
