Because if I remember right something like 90% of Americans profess to have a belief in God. Now of course that doesn’t mean that 90% of Americans reject evolution, but it does mean that we are open to the belief in a higher power that directs the universe and are at least somewhat likely to accept someone else’s mainstream religious views.
Yes, that's true. More folks in America are supposed to believe in God than any other country according to the DBM and their polls. I don't have a problem with it.
