Robert, even if you hadn’t stated elsewhere your opinion that the fields of biology, palaeontology and geology have no bearing on each other, and implied that evidence from any of these fields of study is of no value in helping humans understand the history of this planet and the living organisms on it, this claim of yours would amply demonstrate the depths of your ignorance, and your indifference to truth and logic. It is as absurd as if you were to cheerfully assert that William the Conqueror defeated Charles I at the Battle of Waterloo. It makes no sense whatsoever in terms of even a Young Earth Creationist narrative. If the K-T geological boundary marked the point of your biblical global Flood, as described in Genesis, when supposedly all humans bar Noah and his family were wiped off the face of the earth, along with all terrestrial animals and birds bar those on the Ark, why do you imagine it is that there are absolutely no fossils of humans, or any other modern mammal family – no apes or monkeys, no dogs, bears, horses, rabbits, kangaroos – in any rocks BELOW the KT boundary, or immediately ABOVE the boundary? There are plenty of fossils from earlier geological periods – the weird and wonderful creatures of the Burgess Shale, the trilobites, ammonites, plesiosaurs and ancient fish of Dorset’s Jurassic Coast, and on land the giant dinosaurs you claim were actually birds (or possibly egg laying rhinos), and flying reptiles, and mammals of the approximate size and apparently similar life style to modern tree shrews. No bigger mammals.And no humans, even though the whole purpose of the Flood was supposedly to wipe them out. And no human fossils in the rock strata immediately ABOVE the KT boundary, either. Or ravens or doves or sheep (or goats or cows or whatever other animal YECS imagine it was that according to Genesis Abel farmed and made a sacrifice of to the Lord) for that matter. There is no fossil trace, IOW, of any humans, or any of these other creatures mentioned in Genesis as existing before the Flood or at the time of the Flood, to be then wiped out globally except for their representatives on the Ark, having existed either BEFORE the KT boundary, or for millions of years after it, let alone of any of them dying in a flood or any other way at the time of the KT extinction event.
