Example text

Great years represent the divine equivalent of ordinary years for mortals. Rather than being measured by the time it takes for the Earth to travel around the Sun, they comprise instead the period in which the planets (those known at that time) repeat their relative morions in the sky. In other words, one Great Year is the interval between two complete alignments of all of the planets. Babylonian mythology distinguishes between times in which the planetary alignment takes place in the part of the zodiac known as Cancer, and times when it occurs in Capricorn.

First of all, there are no indications in the geological record of a deluge of such universal proportions. Surely evidence of such a catastrophic event (if it had occurred) would be omnipresent in the rocky strata examined by geologists, much more so than the isolated examples of uprooting that they have observed. And further, if a comet or asteroid caused the flood then there would be global connections in the rock record between collision debris and residue from a deluge. Also, scientists, such as D.

Acknowledging that there is no geological evidence that glaciers formed during the late Cretaceous period, Napier believes that the dusty shroud produced by the supercomet's sublimation was not thick enough to spawn a full-fledged ice age. Rather, he thinks that the debris served to cool off the Earth substantially—sufficient, over time, to obliterate the dinosaurs—but not enough to generate glaciers. Thus, in Napier's view the period in which the saurians died out was a "frost age" rather than an actual ice age.
