One is perplexed trying to figure out what you are really asking or what your point really is. One assumes that you think this is some sort of "evidence" that the earth is only 6,000 years old or some other such nonsense. *sigh* The thing, scientists are often wrong, that's part of science. Any hypothesis that cannot be proved wrong is not really an hypothesis. That's why the "science" of religious folks isn't actually science. There are no disprovable hypothesis, only statements based on faith.

vacuum cementing. The dust is held together by the vacuum between the particles, and the force actually cements the dust together. The dust becomes rocklike. The dust is still there, but most of it is solidified into rock.

Angels have no need to whip out their vacuums and do their weekend lunar cleaning. Not only do creationists typically cite the same obselete study, but scientists were well aware of the amount of moon dust by the time they made their lunar landing. I've copied and pasted an excerpt from Talk Origins concerning the huge flaws in the study, which I think was conducted some time in the 60s. "Pettersson stood on a mountain top and collected dust there with a device intended for measuring smog levels. He published calculations which measured the amount of nickel he collected, assumed that nickel was only present in meteoritic dust, and assumed that some percentage of meteoritic dust was nickel, to get his final figures (that first assumption was wrong and caused his published figures to be a vast overestimate)." His final results showed 15,000,000 tons but his publication said it was only 5,000,000. Even after his study was exposed as being faulty, creationists continued to use the high end of his estimations.
