Continuing the discussion from Interpretation & Meaning in Genesis + Sabbath:
@Timtofly Given we have wandered rather far afield from the topic I thought I would start a new thread.
The canyon was formed by the river. How could it have nothing to do with the age?
Since the current river has cut through all the way down to the basement rocks all of those layers had to exist before the river started to form the canyon.
That area has actually been under an inland sea several times in its history. There are layers that were formed and contain marine fossils. Other layers contain wind blown sand and fossils of land animals that include their tracks and remains of their nests so we know it didn’t form under water. And then there are further layers formed under the sea.
The layers also contain evidence that rivers eroded channels in the older layers. These channels contain boulders from layers above them and then are filled in with sediment from even higher layers.
Exactly how could a sea help? There is no flowing water, which is what forms the river channel, in the sea.
Figuring out the correct time frame is a matter of making measurements and being honest in reporting the results. The Bible demands this so yes it does matter.
What evidence do you have that a sea can form in a short period of time?
Flooding doesn’t form a meandering river. We know the types of rivers that are formed as the result of a large flood and they do not form meandering curves. Look up Channeled Scabland. Here is a link.
