Drills were used that turned 500X faster than today's power drills and bored into granite rock with ease.
Uh, no.
Dentists worked with cement fillings, dental bridges, and inserted artificial teeth.
Tooth drilling, tooth pulling, fake teeth, attempts at putting in fillings, all true.
Doctors performed pregnancy tests, determined the sex of an unborn child, fed nourishment through tubes, fitted artificial legs and hands; and used anesthetic and sophisticated instruments to perform bone and brain surgery?
Trepanning was done apparently for health reasons. A good many were successful, most probably were not. Anaesthesia was carried out via some mediciinal herbs, and by "stunning with smoke". Results overall were hit and miss. Prosthetic legs, feet, toes, are known from ancient Egypt. Not sure about the rest of those claims, but am doubting it.
Mysterious moving walls, automatically flashing lights and lamps that shone century after century, non-stop?
Never existed.
A detailed map of Antarctica dating back thousands of years, without ice!
Doesn't exist. The two maps generally referenced don't show Antarctica without ice, or don't show it at all.
A 400 ft pyramid was found on the seabed.
If this refers to the natural formations in deep water off Cuba, then no.
44 skeletons were excavated in Pakistan dating to about 2000BC and found to be radioactive!
Nope, there were no radioactive skeletons excavated at Mohenjo-Daro or anywhere else from ancient India or Pakistan.
There are 25 places around the world which show hard evidence that atomic warfare was used thousands of years ago.
There is not even one. This is related a bit to the radioactive skeletons -- the most obvious guess from the Mahabharata texts is that bolides (basically space debris) rained in from the sky.
In Peru, 4-dimensional art with several faces that disappear or change into other figures, according to your position or that of the sun.
No idea wth this is really about, best guess is Markawasi.
Dinosaurs and people coexisted.
Dinosaurs and people did not coexist. I'd be happy to learn that some kind of humanoid species (or more than one) walked the Earth long before homo sapiens, but alas, there is no consistent, solid evidence. The claim probably relates to the all-dinosaur prints at Paluxy TX.
There are approximately 600 legends worldwide that a world flood took place about 4,400 years ago.
There are legends of large flood or tsunami events, here and there from preliterate traditions, but not even one of them agrees in every detail with any of the others.

Oh come on now. You know that’s not a real disqualifier.

You take any sized group of witnesses to any crime or major catastrophe and you’re gonna have at *least* as many descriptions as members of that group.
