The sedimentary layers do NOT support evolution and long ages. First a quick preface by Tas Walker...
Walls of Grand Canyon expose sedimentary strata, laid down by water.

Expected erosion missing
Layers are missing
Erosion should produce irregular surfaces
An example near Grand Canyon
Gaps are not obvious
“A puzzling characteristic of the erathem boundaries and of other major stratigraphic boundaries [boundaries between differing fossil assemblages] is the general lack of physical evidence of subaerial exposure. Traces of deep leaching, scour, channeling, and residual gravels tend to be lacking, even when the underlying rocks are cherty limestones … these boundaries are paraconformities that are identifiable only by paleontological [fossil] evidence.”3
“I was much influenced early in my career by the recognition that two thin coal seams in Venezuela, separated by a foot of gray clay, and deposited in a costal swamp were respectively of Lower Paleocene and upper Eocene age. The outcrops were excellent, but even the closest inspection failed to turn up the precise position of that 15 Myr gap.”6
Gaps are semi-continent wide
“The accumulation of the present stratigraphic record [sedimentary rocks] in many cases involves processes that have not been, or cannot be observed in modern environments … there are the extreme events … with magnitudes so large and devastating that they have not, and probably could not, be observed scientifically.”7
