The easiest way to delete millions of years from geological history is to recognise the contact between two sedimentary layers for what it is. If the contact surface is flat that is powerful evidence that the upper layer was deposited immediately after the lower one. If any significant length of time separated the depositional events then the boundary would be eroded and not flat.
A second easy means to delete millions of unnecessary years from the geological record is to recognise that a graded bed must have been deposited all at once. A graded sedimentary layer is most easily explained by a single event that has sorted the entire layer.
A third easy way to delete millions of years from the geological record is to recognise that deposits of high purity were deposited quickly. There is no slow mechanism that might account for a depositional layer constructed almost entirely of only one source material.
These are three simple and powerful ideas that negate the popular requirement that one must believe rocks took millions of years to form.
The problem is not the empirical data but the presuppositions that are used to interpret the data.
