Theoretical physicist Stephen Hawking said in November we have about 1,000 years left on Earth before climate change and nuclear weapons make life on this planet unsustainable, all the more reason to explore other possible homes in the universe. In Expedition New Earth, a forthcoming BBC documentary, that forecast gets shortened to 100 years.
Not that Creationist Ken Ham is worried. Why freak out about science when the only thing we have to fear is whatever the Bible says?
Who are you going to believe: The man whose life has been dedicated to exploring the boundaries of science or the man whose entire mode of thinking exists fully outside those boundaries?
You would think Ham would be more receptive to concerns about impending doom. Even Noah built an Ark before the flood hit.
