ORIGINAL: Consecrated2God I do remember one thing they brought up, though, which is the amount of salt in the oceans. The creation scientists say that the ocean is getting saltier, and that if the earth was very old it would be all salt by now. There are other things I remember them talking about, too, such as the amount of dust on the moon. These are both very out of date arguments. In fact, in the link you gave to AiG there is an article explaining why the moon-dust argument is no longer a valid one to use. The problem with the salt argument is that you have to deal with all mineral salts. And depending on which salt you use you can get an alleged age of anywhere from hundred of millions of years (for sodium) to only 100 years (for fast-reacting aluminum salts). See this table from http://www.talkorigins.org/faqs/faq-age-of-earth.html#ocean Al - 100 years Ni - 9,000 years Sb - 350,000 years Fe - 140 years Co - 18,000 years Mo - 500,000 years Ti - 160 years Hg - 42,000 years Au - 560,000 years Cr - 350 years Bi - 45,000 years Ag - 2,100,000 years Th - 350 years Cu - 50,000 years K - 11,000,000 years Mn - 1,400 years Ba - 84,000 years Sr - 19,000,000 years W - 1,000 years Sn - 100,000 years Li - 20,000,000 years Pb - 2,000 years Zn - 180,000 years Mg - 45,000,000 years Si - 8,000 years Rb - 270,000 years Na - 260,000,000 years Moreover, these are residence times, not accumulation times i.e. they don't measure how long it takes this much salt to get into ocean water, but how long it stays in dissolved form--on average-- before it is removed from ocean water. So in fact, these figures have nothing to do with the age of the earth. Austin & Humphreys argument is summarized and briefly answered here with a link to a more detailed analysis by Glen Morton. http://www.talkorigins.org/indexcc/CD/CD221_1.html
