All it would take is one tree to demonstrate otherwise (even though the title of this thread is plural).
Just saying 'debunked' is not cutting it with me.
Then find one tree that does demonstrate this. Until any evidence of the claim is actually presented, it is debunked.
Maybe one or two forests were 'debunked', but let's not throw the baby out with the bathwater, eh?
Once again, find me some evidence of polystrate fossils in sediment separated in layers ordered by depth.
By permeating multiple layers vertically, it would show the layers not to have been laid down over millions of years.
As I have explained, that is not evidence of a global flood. You can perform the experiment I explained to you, and you will not find the layers of sediment that we see in the real world.
One explanation for polystrate fossils is called a volcano. When a volcanic eruption occurs, a lot of dust and ash is launched into the sky. This dust/ash then falls to the ground and builds up into thick layers. Perhaps then the molten lava flows down and sets hard over the fossil, creating your polystrate fossils.
No idea how correct that is geologically, but I'm not a geologist. Pretty sure that video gives a better explanation than I do.
If the trees were buried over the course of millions of years, where are their trunks?
I don't understand your argument here. Could you be a bit more clear? Perhaps some evidence of a tree that doesn't have a trunk that is a polystrate fossil?
Perhaps they resurfaced when Pangaea got broken up in Genesis 10?
What? Is this another crazy interpretation of genesis?
Did the heavy rock that sunk down on the bottom magically float up a few layers to form our sedimentary layers?
You say Genesis 10 explains Pangaea broke up, then I gather you accept the fact of Pangaea, and that fact was found by tracing back the path of the continents over millions of years. Genesis from my last interpretation stated the earth was made within 6 days. If you want to use the fact of Pangaea you must also accept the fact that goes along with it. Otherwise you are just cherry picking.
