The myth of Noah's ark is silly, but it's amazing what mental corkscrews people will turn themselves into in order to make the story credible, at least to the credulous. The land masses haven't changed appreciably in the past 10,000 years, and we certainly have evidence that no water covered the Greenland ice sheet. Mount Everest would have been exactly 400 feet shorter than its present 28,000 feet. In order for water to cover this mountain in a global flood there would need to be more than five miles of water above the present level. If this water fell as rain in only 40 days that would mean rain fell at an average of 6 inches per minute, every minute of every hour. Where did this water come from, and where did it go..? The greatest 24 hour rainfall on record happened in Mumbai, India during the monsoon season where 37 inches fell in 24 hours on July 26, 2005, and that's only 1.54 inches an hour.
"God told the patriarch to coat the ark, both inside and out, all 229,500 square feet of it, with pitch, and, in fact, this was a common practice in ancient times. But when Noah hurried to the corner hardware store, the shelf was bare, for pitch is a naturally occurring hydrocarbon similar to petroleum (Rosenfeld, p. 126), and we know that oil, tar, and coal deposits were formed when organic matter was buried and subjected to extreme pressure during the flood (Whitcomb and Morris, pp. 277-278, 434-436), so none of it existed in the prediluvian world. Morris (1976, p. 182) tries to say that the word for "pitch" merely means "covering," but not only do all other Bible dictionaries and commentaries translate it "pitch" or "bitumen," but creationist Nathan M. Meyer reveals that all the wood recovered by arkaeologists on Mt. Ararat is "saturated with pitch" (p. 85). Thus it seems that God accommodated Noah by creating an antediluvian tar pit just for the occasion, and we have another miracle."
