Young Earth creationism (YEC) is the belief that the God of Judaism or Christianity created the Universe, the Earth and all life on Earth over a short time between 5,700 and 10,000 years ago. Those who believe young Earth creationism are mainly Christians and Jews. They believe the Genesis account of creation in the Bible is completely true. Young Earth creationists believe that God created the Earth in six 24-hour days. They disagree with other creationists because they believe the Bible is literally true when it tells the age of the Earth.
