Young-Earth creationists believe that the Earth is between 6,000 and 10,000 years old, again as described in Genesis. Most believe that the universe is the same age as the Earth though some admit it may be older.
Day-Age creationists hold the view that the ‘six-days’ of the Book of Genesis are not ordinary 24-hour days but instead are periods of time that could be the equivalent of millions of years.
Neo-Creationists aim to move away from the other forms and hope to find a formula that is more palatable to the general public. They aim to re-frame the debate about the beginnings of life in non-religious terms and without appeals to Scripture.
