Yes, I know, "The only stupid question is the question which doesn't get asked."
Still, I'm afraid some of you will think this is stupid:
How could Paleozoic soil be older than Mesozoic soil, which in turn is older than Cenozoic soil?
Do volcanoes erupt newer soil over older soil?
Does the Earth receive newer soil from meteor showers, or what?
I feel hypocritical arguing that dinosaurs are found only in Mesozoic soil whereas cavemen are found only in Cenozoic soil; therefore cavemen could not have walked the earth alongside dinosaurs.
Could someone please tell me what I'm talking about?
