Scientific Red Faces

Some years ago scientists discovered human bones in California buried under thick layers of mud. Scientific authorities studied the bones and dated them at about 75,000 years old. Digging deeper, scientist discovered an old United States Army button! Was the U.S. Army around 75,000 years ago, or was the dating method unreliable? More recently an archaeological team from a Japanese university discovered drawings on a cave wall on a Japanese island. This important discovery was dated at 10,000 to 13,000 years old. When one of the local residents of the island heard about the discovery, he stepped forward to confess that as a boy he often drew on the walls of the cave with charcoal.

From an ICR (Institute for Creation Research) article, they quoted from
Jackson, Wayne 1990, Scientific red faces, Reasoning from Revelation, v. II, n. 1, Jan p.3

I trust ICR, but if anyone reads this and shows that one of these is an urban legend, I will quickly remove it from this post.
