Gunung Padang is a pyramid in Indonesia. It’s being excavated by archaeologists, who are apparently scornful of it.
Dr. Danny Hillman Natawidjaja is one of them, and the Indonesian government approves. Apparently, carbon dates in the pyramid go back 26,000 years, far before pyramid-building technology was wide-spread or even extant.
However, what the video doesn’t tell you is that carbon dating is notoriously unreliable, and finding a very old carbon-date inside a pyramid means very little, as most megalithic sites are built up over thousands of years, so of course the center will be very old.
