Does a receding moon equal a young Earth?
CLAIM: Tidal friction causes the moon to recede from the Earth at 4cm per year. It would have been greater in the past when the Moon and Earth were closer together. The Moon and the Earth would have been in catastrophic proximity (Roche limit) at less than a quarter of their supposed age. (Answers in Genesis, n.d. ) (Batten, 2019 ) (Baugh, 1989 , p.10-11) (Ferrel, 2006 , p.135) (Ham, 2008 , p. 98-99) (Ham, 2010 , p.189-190) (Hovind, 2003 , 1:13:49) (Miller, 2019 ) (Petersen, 2012 , p.58) RESPONSE: One of the more popular claims in young-Earth creationist literature is that the Moon's recession from the Earth imposes a strict limit on how long it could have been orbiting our planet. This argument hinges on the Moon gradually receding from the Earth at a semi-steady rate of about 4cm per year due to tidal interactions caused by the Earth's oceans. As the argument goes, if this rate is extrapolated backwards, the Moon would have been in contact with the Earth's surface o...
