Bad Claims: The Recession of the Moon
Of course, some presentations of this are worse than others. In this one Thunderf00t lambastes a particularly bad example of the claim/argument, but he does cover rather tidily the issues involved.
And here’s one where Desertphile does an excellent job of explaining why the extrapolation based on no evidence is outright intellectually dishonest; he also goes into some of the evidence that makes the extrapolation obviously incorrect.
This bad argument has been floating around for some time. It’s a gross misunderstanding of astronomy promulgated by Answers in Genesis to the credulous and those with little scholarship in any of the sciences needed to understand it. The biggest problem with this argument—and it’s not really an argument; it’s more like an unsupported claim—is that it rests on a faulty premise: The moon has been receding from the Earth at the same rate since it’s inception.
