I used to be a Uniformitarian but now I'm a Baptist.Seriously, only a tiny minority of Christians swallow this "young earth" stuff. The Bible doesn't say how old the earth is but in several places describes things as ancient or age-old using the Hebrew word olam,
Gen 49:26 Your fathers blessings are greater than the blessings of the ancient mountains, than the bounty of the age-old hills." NIVStrong's defines the word olam as:"properly concealed, that is, the vanishing point; generally time out of mind (past or future), that is, (practically) eternity; frequentative adverbially (especially with prepositional prefix) always:always (-s), ancient (time), any more, continuance, eternal, (for, [n-]) ever (-lasting, -more, of old), lasting, long (time), (of) old (time), perpetual, at any time, (beginning of the) world (+ without end)"James Strong, Strongs Hebrew and Greek Dictionaries, Electronic Edition STEP Files Copyright © 1998, Parsons Technology, IncIf the hills were old beyond old, then how could they be only several thousand years old when these passages were written?The Young-Earth Creationists really don't know the Bible very well at all.
