<<when you look at a bat, you either have to accept the theory of evolution, or you have to believe that one day God woke up and exclaimed "I know what we need! A Gerbil with a hang glider!!">>
Terry Pratchett has a very good take on that in one of his many books - how all the little things were designed
However, I'm firmly in the Evolution camp and I do love bats. They fly around here but we haven't seen a roost or a hibernation place yet. Here it's swallows coming in for a nosey - my 93 yo aunt caught one yesterday in her granny flat, to put back outside and is well pleased with herself
