The Paracas skulls are no different than other human skulls except for the purposeful deformation. Foerster deliberately lies about this. He makes his living touring naive ignoramuses through these "mysterious sites" so he's certainly not credible.

Graham Hancock has openly admitted that he did pretty much no research whatsoever when writing "Fingerprints of the Gods?"
