Thursday Quotable: Good Omens: The Nice and Accurate Prophesies of Agnes Nutter, Witch

Welcome to Thursday Quotables! This weekly feature is hosted by Bookshelf Fantasies. Every week we highlight a great quote, line, or passage discovered during your reading each week.

This week's book is Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch by Neil Gaiman and Terry Pratchett. According to these prophecies, the world will end on a Saturday. Next Saturday, in fact. Just before dinner. This book is hilarious and with the small passage I've chosen I hope to show you the humorous style, without giving away anything from the plot.

Current theories on the creation of the Universe state that, if it was created at all and didn't start, as it were, unofficially, it came into being between ten and twenty thousand million years old. By the same token the earth itself is generally supposed to be about four and a half thousand million years old. 

These dates are incorrect. 

Medieval Jewish scholars put the date of the Creation at 3760 B.C. Greek Orthodox theologians put Creation as far back as 5508 B.C. 

These suggestions are also incorrect. 

Archbishop James Usher (1580-1656) published Annales Veteris et Novi Testaments in 1654, which suggested that the Heaven and the Earth were created in 4004 B.C. One of his aides took the calculation further, and was able to announce triumphantly that the Earth was created on Sunday the 21st of October, 4004 B.C., at exactly 9:00 A.M., because God liked to get work done early in the morning while he was feeling fresh. 

This too was incorrect. By almost a quarter of an hour.

And what conclusion do we make out of this passage?

...the Earth's a Libra.
