Re: Nice work so far, but...

Currently I'm writing almost entirely from my own knowledge....
I, for one, have no reason to doubt this. Keep up the step by step. The advantage of having this in a discussion thread, rather than as a set article, is that we non-geologists can ask for clarification on specific points as you go along, as Jar has already done above. So I'm bumping up the thread to encourage you, and because, like many here, I need the lesson!
And a warm welcome to EvC.

Re: Law of superposition (revisited)

Why is it valid to use the law of superposition, which is obvious, and apply it to rocks? Has the law of superposition been observed in this context?
Yes, it can be observed, apart from its obvious logic. "Varve" is the word given to annual layers of sediment or sedimentary rock, and there are many places, usually lakes, where these are still being laid down.
Here's a brief explanation of varves, including a nice picture of some old ones which have been uplifted.

The problem I am having with the LoS, is that from a creationists view, the LoS doesn't apply to geology.
The Matt defining the Law of Superposition writes:
This states that sedimentary layers form in a time progressive sequence with the oldest layers at the bottom and the youngest on the top.
I explained varves to you in a post above. Annual layers of sediments can be observed in real time accumulating on lake beds with, logically, the oldest on the bottom and the youngest on the top, in accordance with the Law of Superposition.
So, if the LoS, from a creationists view, does not apply in geology, then you can see these varves as a strong indicator that the creationist view is a false one, as it doesn't fit the evidence.
Vashgun writes:
You probably don't even think there was a flood. So, for me to accept the application of this LoS I would need to agree and submit to your ideology.
Reality isn't ideology, and ancient Jewish mythology isn't reality. If you choose to believe in one of the ancient creation mythologies, Jewish or any other, of course it won't fit in with geology or any other branch of the sciences. That's because superstitious, ancient cultures tended to make things up to fill in the gaps in their knowledge.
It isn't the job of science to fit in with the superstitions of any ancient culture.
