Chick's idea of dinosaurs dying out because the air was thin is yet another in the series of Creation Science ideas that, even if you ignore all the scientific inaccuracies, just seem totally unnecessary. I would imagine that most, if not all, Creationists accept that God is omnipotent. So couldn't He just as easily make fossils appear out of nowhere, or dinosaurs just magically die out all of a sudden, WITHOUT any pseudo-scientific explanation? I guess the Creationists are hoping that working vaguely scientific concepts into their beliefs will make their beliefs more acceptable to the secular world. But what's even weirder is how they'll insist that these concepts are on par with the actual Bible, even though there's no mention of them in there. You can't be a TRUE Christian unless you think there was a time when people ate dinosaurs for dinner.
On a completely unrelated note, I have now read two Oz stories by Vincent Ward (apparently also known as Michael Vincent), Beany in Oz and Mrs. Pickering in Oz. The former is about a black orphan boy (specifically identified as black in the first sentence) who speaks in seventies slang (including the term "jive turkey") journeying to Oz. The latter has the author visiting the magical land, along with two children and an old woman (i.e., Mrs. Pickering herself) from his town. Both of them have some interesting ideas (the mysterious train ride in Mrs. Pickering being one of my favorites), but they could have used a lot of editing. Also, some bits in Mrs. Pickering in particular seem derivative of parts of other Oz books, like the giant child who acts like Elma from The Hungry Tiger of Oz, and the sorcerers' attempts to stop invaders with dangerous animals being quite similar to the Wicked Witch of the West's actions in the original Wizard of Oz. There's also a little too much use of odd communities being suspicious of strangers (and, in these particular stories, thinking they're spies). Another odd thing about Mrs. Pickering is that there seems to be an unusual amount of religious symbolism, as the children as named after saints, and the story revolves around a quest for a Golden Cross.
And now I suppose I should go to bed. Good night. Unless you're reading this in the daytime, in which case I'll say "good day" instead.
