Sahara Desert is expanding (Talk.Origins)
From CreationWiki, the encyclopedia of creation science
- The Sahara Desert is expanding at such a rate that it can be only a few thousand years old, indicating a young earth.
Source: Hovind, Kent, n.d. Universe is not "billions of years" old.
CreationWiki response: (Talk.Origins quotes in blue)
1. Yes, the Sahara Desert is only a few thousand years old. What does that have to do with the age of the earth?
Talk Origins is correct here. The age the Sahara Desert does not prove a young Earth, but that is not what Hovind is saying. His point on the expansion of the Sahara Desert is that it shows that its age is consistent with the Genesis Flood, and not that it proves a young Earth.
On a side note, the Namib Desert(which has some of the world's largest sand dunes) appears to only be 5,700 years old. Of course this assumes the absense of a global flood.
