Young Earth Creationism (YEC) is a belief that the Earth and all life on it were created by God over a relatively short period, typically interpreted as six days, as described in the Bible. Proponents of YEC argue that the Earth is only a few thousand years old, rejecting scientific evidence from fields like geology and evolution that suggest the Earth is approximately 4.5 billion years old. YEC supporters often promote a literal interpretation of the Genesis creation account and may challenge mainstream scientific theories. They believe that scientific findings should align with their religious beliefs, leading to debates between YEC and the scientific community.
