and for the record, I don’t mean to come down on the side of old-Earth creationism. I recently was inspired by a Freeper to a notion that maybe God made the world SEEM old because he wanted to reveal the nature of things. Just like Adam, if he were truly human, had a body which seemed to be the result of physiological processes of maturation, so too would the Earth and skies seem like they were the result of cosmological processes of maturation.
Of course, once you start getting into quantum stuff, then you can get these concepts to merge into one another: Is ours a young Earth created to seem old or an old Earth gone unseen except by a creator who declares what day and night are for his own purposes?
The Earth seems old only to those that fail to closely observe day to day changes in the Earth. The most obvious example of this is storm-caused land slides. The frequency, and extent of these slides illustrates a very young Earth, since were the Earth more than 5000 - 6000 years old, all the soil necessary for agriculture would now be at the bottom of the oceans.
If you need more to sharpen your vision, search the term "small comets" and be prepared to be astonished; science, as science, rather than propaganda, proves the young Earth conclusively.
