There is a priceless contradiction between the creationists here. On the one hand Jehu thinks that millions of years of the pre-cambrian explosion aren't enough; OTOH derheim has every species on earth exploding (from what could be saved on a 450ft boat with all the food for those animals and plants for a year, and food for all the predators for years) in the first 1000 years or so following the disembarkation since we can't see this explosion continuing now and there is no historical record of it. Hilarious.
My arguments are my own unless otherwise stated. Noah's Ark is another issue which we can take up if you wish.
