In 1987, paleontologist Jerry MacDonald discovered a wide variety of fossilized tracks from several different species of animals and birds, located in a Permian strata. Among the various fossilized tracks were the clear prints of a human foot.
However, the Permian strata has been dated from 290 to 248 million years ago- millions of years before animals, birds, dinosaurs, and yes, man, was supposed to exist. How then can these prints be explained?
In July 1992, the Smithsonian Magazine had an article on these tracks called "Petrified Footprints: A Puzzling Parade of Permian Beasts". The magazine acknowledged the mystery, acknowledging "what paleontologists like to call, 'problematica.'" It described what appeared to be large mammal and bird tracks that, "evolved long after the Permian period, yet these tracks are clearly Permian."
While it is commendable that MacDonald and the Smithsonian clearly acknowledge the existence of these tracks in a strata that contradicts the current evolutionary theory, it is noteworthy that they highlight only the mammal and bird prints, and don't mention the human footprint found with them.
Interestingly enough, since these tracks have been discovered, evolutionists have not tried to argue their authenticity or debunk them. Nor have they tried to argue that the footprint isn't human. (Often they claim that it's a print that just "looks like" a human footprint.) Their very silence is deafening.
