This is assuming perfect environment. What if's abound. Example, your cat got a clever idea and decided to put the top on on the bottom. Or the maid mixed the top two out of spite for her poor employment wage. How is that each layer represents a certain age? More to the point; How is it that this is a law of geology? Wouldn't you have to have a foundational religion..., say, uniformitarianism? For this to even hold water?
I am concerned that you are flooding too many threads without having enough understanding to be able to read the posts you are responding to.
If this continues you will receive short suspensions.
I suggest you pick a particular, basic topic and stick to that one until you learn a bit about the topic involved. If you wish you may set up a "great debate" thread which can be restricted as to who is allowed to post with you on it. This simplifies your task by reducing the volume of replies and often keeps the focus.
Most of your posts make very little sense. You need to slow down and think through your replies more carefully.
