ok two points in answer to the JW style exhuses:
1) God was very happy to give his profets visions and dreams that featured monsters and giant lizard type creatures.... so whats the problem with addmitting to the people of the time that they once existed?
2) The dinos were very destructive creatures, particularly to the O zone layer, i think i heard somewhere that they farted almost constantly and therefore could have achieved their own global warming and ultimatly brought down themselves and their species.
aha! i hear the JW's cry... so the dinos did have a purpose! God put them on the earth, to bring about global warming and warm it all up for us! Well that could be true but you have to think to yourself, surely if god wants to warm up the earth, hes capable of doing it without needing to create huge lizards that fart continuosly for millions of years until they destory themselves!??
