"He believes the Mesoamerican pyramids and Egyptian pyramids are built by the same people as the Visočica hill... Osmanagić wishes to excavate in order to "break a cloud of negative energy, allowing the Earth to receive cosmic energy from the centre of the galaxy""
The wikipedia article contains plenty more attacking the content of his assertions, including this letter:
"We, the undersigned professional archaeologists from all parts of Europe, wish to protest strongly at the continuing support by the Bosnian authorities for the so-called "pyramid" project being conducted on hills at and near Visoko. This scheme is a cruel hoax on an unsuspecting public and has no place in the world of genuine science."
His gobbeldegook about cosmic energy is a lot more fun and a shorter quote, so I went with that instead.
