Baloney. There is no way to date the layers. But the evidence is overwhelming that the layers were deposited rapidly, on top of each other. The flatness and purity of the layers is evidence of hydrologic sorting:
Similar flatness and purity can be found in the coal layers:
A unique feature found in many coal layers are thin coal seam benches. A bench is a sedimentary rock layer between coal seams. Some benches are only a few inches thick, which rules out the "swamp" theory of coal formation.
Another problem with the uniformitarian theory is missing layers. Approximately 100 million years of layering is missing between the Muav and Temple Butte limestone in the Grand Canyon.
Strata are typically flat (e.g., the same thickness, everywhere), yet they should show extensive erosion over long periods of time. There is also virtually non-existent bioturbation (from soil-boring critters), which should be common in these sedimentary layers.
There are also marine (ocean) fossils in almost every sedimentary layer, including the top ones. That in itself is evidence of a global flood.

Kalamata:
"Baloney.

The flatness and purity of the layers is evidence of hydrologic sorting:" There are dozens of different methods to date geological strata, all of which produce consistent ancient-earth results.
As for "flatness and purity", you yourself have posted a photo of layers which are anything but.
Finally, this whole suggestion of "hydrologic sorting" is pure fantasy, precisely the kind of conjecturing you claim science is not supposed to do, right?
Kalamata: "Similar flatness and purity can be found in the coal layers:"
And yet, in no conceivable way can coal layers be explained by alleged "hydrologic sorting".
Kalamata: "A bench is a sedimentary rock layer between coal seams.
Some benches are only a few inches thick, which rules out the "swamp" theory of coal formation."
Complete rubbish, since swamps can quickly come & go, as water levels rise & fall.
Kalamata: "Another problem with the uniformitarian theory is missing layers.
Approximately 100 million years of layering is missing between the Muav and Temple Butte limestone in the Grand Canyon."
Wait, 100 million years missing from a young earth?
No, that's only inexplicable to your fantasy "hydrologic sorting".
In real geology it simply represents a geological period without deposits at that particular site.
"The next two periods of geologic history, the Ordovician and the Silurian, are missing from the Grand Canyon sequence.[25]
Geologists do not know if sediments were deposited in these periods and were later removed by erosion or if they were never deposited in the first place.[31]"
It happens I know a little about Ordovician and Silurian deposits because years ago I went fossil hunting there near Niagara Falls.
Their missing from the Grand Canyon simply says the land then wasn't under water (more likely, imho), or such deposits as were made, later eroded away (possible).
This map shows Silurian deposits in New York and near the Grand Canyon, but not necessarily in it.
Kalamata: "Strata are typically flat (e.g., the same thickness, everywhere), yet they should show extensive erosion over long periods of time.
There is also virtually non-existent bioturbation (from soil-boring critters), which should be common in these sedimentary layers."
Strata are typically laid down flat but often then folded into synclines & anticlines, which do erode considerably.
"Bioturbation" is sometimes found in fossils, here are two examples -- Stromatilites and Planolite:

It's evidence that those layers were under water when formed.
