Actually, it was 2 of every unclean animals, and 7 of all clean animals...what God deemed as food for humans and what he did not. This doesn't neccessarily translate to wild and domesticated. For example, deer are clean animals, but wild. Pigs are unclean animals, but generally considered domesticated.
And the bible speaks about "kinds". For example, wolves, coyotes and dogs are all of one kind. He would only have had to have one representative. Many animals would not have needed to be on the ark, such as aquatic animals, fish, etc.
So, are you saying that poodles and wolves, Great Danes and chihuahuas all had a single common ancestor 4,000 years ago? And that freshwater and saltwater fish all enjoyed the same environment for a year?
Doug, how did all the marsupials from Australia get to Noah, survive without their native foods, and get back to Australia?
Add in about 50,000 other species from all over the globe.
Its a story. If it were true we could replicate it. Go ahead, build an ark that can hold 2 of each animal and sail it for a while, using the tech of the day. Then get back to me on how well it went.
