There are some claims and reports of human artefacts and remains in rock layers that are clearly part of the Flood sediments. However, many of these claims are not adequately documented in any scientific sense, while those few reports that have appeared in the scientific and related literature remain open to question or other interpretations. For example, the book Ancient Man: A Handbook of Puzzling
Artifacts' looks like an impressive and voluminous collection of such evidence, but on closer examination many of the artefacts, though puzzling archaeologically, still belong to the post-Flood era, while other reports and claims are either antiquated or sketchy and amateurish.
