And a true one. If I were to visit your home I would not find your personal records of a geologic column; your own digs and your own findings. I dare say you've not ventured outside you home to dig a hole more than ten feet deep. Or have you?
Who thought up the geologic column? I'm sure there are several intellectuals who could be named. It's not a bad idea. It just hasn't been demonstrated in real life, just like the processs of evolution.
