That Mary Dawson person they quoted in the article puts it best by saying: "Genesis is not science ... Genesis is a tale that was handed down for generations by people who really knew nothing about science, who knew nothing about natural history, and certainly knew nothing about what fossils were.''
Ken Ham really needs to carefully consider that fact.
His "creation museum" is a piece of trash.
(Oops, I'm a blasphemer now.)
So maybe he's right, and the Earth is only 6000 years old -- but God can't blame me for believing otherwise when every single scientific fact known to man suggests that the Earth is billions of years old.
