Creationists believe in a literal interpretation of the Bible. They believe that the Book of Genesis provides a true and accurate account of the beginning of the world. They believe that the Earth is 6000 years old, that we are all descended from Adam and Eve, and that we are all sinners because Adam and Eve succumbed to temptation by the snake to eat of the fruit of the Tree of Knowledge, in defiance of the command by God not to eat thereof. As an atheist, I believe it is poppy-cock. A quaint story, to be sure, and a far more interesting story if viewed as allegory, as liberal minded Believers are inclined to do.
In the account, God punishes Adam and Eve by expelling them both from the Garden of Eden, Adam (man) is to work the fields by the sweat of his brow, Eve (woman) to be subordinate to Adam and to experience pain during childbirth. The snake is also punished, cursed to go upon his belly. The implication is that the snake was, before then, able to walk. To walk, one must have legs.
In 2000, a fossil of a snake was discovered in Lebanon. New research has revealed something interesting. It is a fossil of a snake with two hind limbs. A snake with legs! So, maybe the Creationists have been right all along, and we unbelievers simply misguided fools? Unfortunately, for the Creationists, no. This fossil is somewhat older than 6000 years; it dates from the Late Cretaceous, about 92 Million years ago. This means it also predates Homo sapiens by about 91.75 Million years. Not so close, and definitely no cigar.
Yay! for science.
