Well, that museum guide was using circular reasoning and should probably polish his presentation to avoid that. However, I think it's great that your cute little sixth grader has studied stratigraphy to the point where he is able to publish monographs critiquing the current state of the field. Look forward to reading the abstracts.
Glad to see you read so carefully what I had to say, oops, guess you didn't, "little lady" sure isn't a "he".
But, I agree the museum guide needs to polish up and update his feeble knowledge of evolution, but then again who can keep up with the every changing facts of evolution, one day millions, the next day billions, the day after birds from dinosaurs, then it dinosaurs from birds.
Thank God the Word of God hasn't changed, we Christians are way to dumb to keep up with the changes the religion of evolution demands of it's servants.
