I (vaguely) remember having difficulty with the concept of 'history' when I was a small child. I imagined the past as some sort of undifferentiated place containing everything and everyone that wasn't here 'now'-- a kind of Parmenidean 'being', static and frozen. In the past, I imagined, cowboys co-existed with dinosaurs. Of course I had only a vague notion of 'linear time' and almost no notion of the age of the world and the universe. And of course at that early age I wouldn't have been able to articulate it like I just have.
It seems that creationists/intelligent design proponents have similarly childish concepts of space and time. Today, for example, I read a blog entry in which the writer exclaimed "Dinosaurs are in the bible!". I can't bring myself to comment on the actual details of the post, but feel free, dear reader, to follow the link and see for yourself what I'm talking about.
