The Toba eruption around 74k years ago which killed so much of humanity that it caused a genetic bottleneck, was not caused by a volcano. It was caused by humans doing some sort of experiment that involved drilling down into the Earths core that went wrong and created a massive explosion that could be seen from space. It completely wiped out a civilization that seemed to at minimum have been on our level of technology, where they had craft that could hover and fly. This was discovered through remote viewing that was done completely blind, meaning the viewer isnt told something like, "ok your target is Atlantis view that". All they are given is a randomly generated reference number, which has been assigned to the target in order for the viewer to view it without having to know what it is in order to eliminate bias the viewer might have in their mind about the target, which leads to the collection of cleaner, more accurate data.
Keep in mind even though the the title of the video is about Atlantis, the civilization that they view does not seem to be Atlantis, but something much older, as Atlantis was destroyed around 11,600 years ago during the Younger Dryas period that involved a bunch or meteors hitting the Earth and melting the ice caps, while this civilization seems to have been ended by a single explosion.
