Very good point, since a global flood would have left the same geological evidence in the same geological strata -

Guess what, that's right it hasn't...thank you for playing stupid myths from archaic superstitions, you have won tonight's star prise, a bible - signed by Jesus Mary
and Joseph, but wait, that's not all, you also get a scale model of Noah's ark, complete with all the million of animals it couldn't possibly have housed, let alone the food, and the environmental requirements, but not to worry, because we are throwing in a year's subscription to creationist monthly, which will explain it all away, and wait for it, a real scale model of the Holy Grail, filled to the brim with faith, an infallible defence against all those pesky facts and all that atheistic science.
