Why do some people believe the Earth is only 10,000 years old?

In short: Young Earth creationism asserts that the planet and all life were created by God within the last 10,000 years. This belief, rooted in a literal reading of Genesis, challenges the scientific consensus of a 4.54 billion-year-old Earth, sparking long-standing debates over science education, biblical interpretation, and the nature of faith.

Young Earth creationism (YEC) is defined by the conviction that the Book of Genesis is a historically accurate, inerrant record. Proponents typically date the creation between 6,000 and 10,000 years ago, often citing the Ussher chronology, which famously proposed 4004 BC. While some modern Jewish theologians and early scholars like Philo have favored allegorical interpretations, YEC movements gained significant traction in the 20th century as a reaction against evolutionary theory.

The movement's modern structure was largely shaped by Henry Morris and John C. Whitcomb Jr., whose 1961 book, The Genesis Flood, revived "flood geology." This theory posits that the biblical Great Flood was a global event responsible for the majority of the Earth's geological strata and fossil record. To reconcile this with physical evidence, some YECs have proposed radical ideas, such as an orbiting vapor canopy or accelerated nuclear decay rates during the Creation week, though these claims have been consistently rejected by the scientific community.

Scientific consensus, supported by geochronological methods like radiometric dating, places the Earth's age at approximately 4.54 billion years. Despite this, YEC remains influential in certain Christian fundamentalist circles, particularly in the United States. Surveys, such as those by Gallup, show that while support has fluctuated—with 37 percent of Americans expressing a creationist view in 2024—the belief remains a point of contention in public discourse, often framed by proponents as a defense against secular philosophies they view as destructive.
