It also doesn't make sense that they used a lump of wood instead of a lump of rock from the earth.
It's a lot more convincing.
Yes, it would be more convincing.
They probably figured that since they were claiming that moon rocks were identical in composition to earth rocks that any old rock on the side of the road would do. They forgot that not everything that looks and feels as hard as a rock is a rock. Petrified wood may feel as hard as a a rock, but it is not a rock. Shame on NASA for being so careless with their hoaxery.
Unless you can provide documentation as to the actual origin of the rock in question, all anyone can do is speculate and speculation is not for proper Zetetics.
The man who gave it to the Prime Minister, Ex-US Ambassador William Middendorf, is still alive. He didn't mention that "oh, it's not a moon rock" to Dutch Broadcaster NOS News when questioned on it. If he had it would have been put into the article.
It was clearly presented as a moon rock. All of these constant RE excuses are really quite unbecoming. One excuse after the next to deflect admission of NASA's scam.
