But skeptics are calling the research into question because there is no current evidence confirming human activity at the Gunung Padang site, in West Java, Indonesia, where the underground pyramid is located.
According to the study, the underground pyramid was discovered using seismic tomography, a technique used to render underground seismic activity into 3D images.
Through this research method, the paper’s authors assert that several underground layers of construction are so impressive that they would completely change our understanding of how ancient civilizations operated during the Paleolithic era.
