Remedial rock works at Gosford Glyphs cause hysteria

The National Parks and Wildlife Service undertook works at the glyphs site this summer as geologists had noticed one of the overhanging rocks was moving and could possibly fall into the crevice where people could be standing.
A large boulder that was holding on by a thread was removed slowly while not damaging the carvings.
Some people were convinced that the council was destroying the glyphs and the internet forums went into melt down with wild rumors and the expected conspiracy BS
Some humble pies were eaten when the site was inspected soon after and no damage could be seen apart from the large boulder gone and the crevice floor leveled out and made a bit nicer to walk on for the not so hardy

The overhanging rock that was threatening to drop onto visitors NPWS have a duty of care to ensure this cannot happen

The sign was posted for months at the site advising of oncoming works

Welcome to 2020 and the Gosford Glyphs are still fake !

Welcome to 2020 and the Kariong Glyphs are still very very fake despite dozens of amatuer Indiana Jones types, conmen and tin foil enthusiasts constructing various web sites and home made YouTube videos not one institution has taken anyone seriously anywhere.
That's because way back in 1984 somebody already did that....
Photos taken of the glyphs in 1984 were shown to Australia's top Egyptologist Professor Nageeb Kanawiati - BA Alexandria, MA Alexandria, PhD Macquarie, FAHA, FRSN,Professor of Egyptology.
Professor Nageeb Kanawiati is Egyptian born and has written around 40 books and articles on the subject and is one of the few archaeologists permitted to work on Egyptian sites.
Professor Nageeb Kanawiati says the carvings at Kariong are not legitimate and are poorly executed by amateurs.
And that's it  - you wont get a higher appraisal from anyone more educated, and since then many experts have agreed.
It's been nearly 50 years since the discovery by locals and around 35 years since they appeared in the media, 35 years since various institutions like the Egyptology Dept Macquarie University in Sydney, the London Museum and the Museum of Antiquities in Cairo were informed of the existence of these carvings in the Australian bush and the world's history has still not been re-written.
So to bring you up to speed - the Kariong carvings are still poor attempts at Egyptian writing that makes no sense at all.
The carvings were done in the last 50 years by up to 3 different parties, the last person caught carving in the cleft was in 1983.
There are no burial chambers or tombs or any other non Aboriginal rockwork at the site.
There were no Egyptians in Australia ever. There is not one scrap of legitimate evidence to suggest that there was or even capable of getting here.
The people pushing the "Egyptians did it agenda" still have absolutely no qualifications in any field relevant to Egyptology and some have a vested monetary interest in pushing their agendas - if there is a payment portal on your favourite conspiracy / pseudoarchaeology website / YouTube channel you are being conned.
The is no government cover up or conspiracy, the government knows, all the top museums in the world know and none of them care ....
