Omphalos hypothesis
The Omphalos hypothesis is the philosophical idea that God created the Earth about 6,000 years ago but with an appearance of old age. For example, rivers which had carved through rock strata, trees with growth rings, and, the classic example, Adam and Eve with navels. The idea was popularized in a 1857 book by naturalist Philip Henry Gosse entitled Omphalos, which itself means "navel."
As science
The omphalos hypothesis cannot be considered a scientific hypothesis. Science cannot distinguish between apparent age and true age.
As religion
The major criticism of omphalos by some Christians is that it makes God a deceiver, i.e. having created something with a false appearance.
Omphalos today
Modern creationists generally reject omphalos as a means of proving a young Earth. Most beleive that the true scientific evidence points to a young Earth. The two major creationist organizations, Creation Ministries International and Answers in Genesis[1], along with the rest of the modern creation science movement, reject omphalos, instead relying on genuine scientific evidence.
