The frustrating thing is that those Ethiopian and Mexican dates and all the others, probably had no more basis for the date than this one. But they build on each other, until some evolutionists will say "there are dozens of cultures known to be 15,000 years old, so the Bible must be wrong.
I for one remain unconvinced. I don't buy the Ethiopian dates, or the Mexican dates, or the Saharan dates.
I don't buy the date for the 150,000 year old fossil. At least they had Argon dating. But then you already know I consider Argon dating to be junk science because of the assumption of the starting amount of Argon, (which has been proven false with 16 different recent volcanic flows), and no way to measure contamination from non-atmospheric Argon.
Of course there are no shortage of opinions. Here is a link to a professor from a Catholic Jesuit university talking about 500,000 year old hand axes in India. He has no problem throwing out the Bible because the axes were probably dated using radiometric techniques.
Meanwhile, I think he's an idiot. I think the radiometric dating is flawed. I think the fossil records and artifacts that would be found had tool bearing humans roamed the earth for 500,000 years would be SERIES HUGH. Thus this professor's misplaced faith in radiometric dating has left him STEWNED.
