Randall talks a lot about a flood happening ~12.000 years ago, during a period known as "The Younger Dryas" (https://en.wikipedia.org/wiki/Younger_Dryas).
Key moments for anyone who doesn't want to watch the 3 full hours are:

0:48:43 Late Pleistocene mortality graph, ~120 species of mega mammals went extinct
0:50:00 Dominant hypothesis of "overkill" or "blitzkrieg" to explain the extinction of the mammoths..
0:52:13 Founding fathers of geology > new school of thought, catastrophism v uniformitarianism
0:54:49 J. Harlen Bretz' proposition of gigantic floods in pacific North West being ignored by peers in 1920
0:56:12 Transition in earth sciences incorporating parts of Bretz his findings, but with a modern example that doesn't scale or compare with Bretz' findings; the new dogma
0:59:36 Joe mentions the problem with the "overkill" hypothesis and Randall adds to it
1:00:05 One of the many mammoth cemeteries
1:01:50 Joe is spooked by Randall's snorting and tries to play it off by referring to the drawing of the "ivory floor" of the London docks covered in Siberian mammoth tusks
1:07:07 Joe asks for Randall's desktop wallpaper, Randall keeps him in suspense for a little longer, shows satellite photo instead
1:11:00 Canada didn't exist
1:14:41 The Bering Strait during Ice Age is exposed, connecting Siberia to North America, 14000-15000yrs ago
1:15:54 Indonesia, modern day v Ice Age
1:16:55 Hundreds of stories that parallel the story of Noah, coinciding with the existing data
1:19:09 if we accept that the stories are based on real events, what do the parts of the persons with foreknowledge imply?
1:19:53 Europe now v during Ice Age, ~15000 yrs ago
1:20:35 Mt. Jumbo, Missoula, Western Montana, shorelines reaching to tops of the hillside
1:21:27 Latreurolle Falls, Basalt layers
1:23:53 West (boulder) Bar giant current ripples, 50ft high
1:25:54 New trend in evidence, geological community is moving in the direction of Randall's assertion, some of the older guard is defending the idea of the jökulhlaups, group of Canadian geologists, John Shaw et al., are challenging this
1:27:50 Where the water for these massive floods came from, asteroidal impact
1:28:45 Impact craters of the last 10.000 yrs, potentially causing massive tsunami's
1:30:45 Modern consensus view of the Younger Dryas, exact match with Plato's account of the subsiding of Atlantis beneath the waves
1:34:20 Recent research, shock-synthesized hexagonal diamonds in Younger Dryas boundary sediments, micro-diamonds, nuclear glass all correlates with massive cosmic impacts
1:35:40 Overspecialisation in modern science, pro's and cons
1:40:02 Listing recent discoveries supporting Younger Dryas cosmic impact hypothesis and narrowing down date to 12.800-12.900yrs ago
1:42:37 Randall mentions gratification as he theorised this 25yrs ago and Joe asks how he became so obsessed with this
1:52:58 What this all means for our species, on a larger scale, big picture, according to Randall
1:53:41 Emerging evidence human population crashed during Younger Dryas
1:55:16 Book of Matthew interesting quote where Jesus talk about what the end of days will look like, what it implies
1:58:33 The moral to all of this, what should we do in terms of consumption of Earth's resources and what to direct our collective efforts at
2:01:34 Error of gradualism in the environmental movement
2:03:27 We'd be fucked without Jupiter
2:03:53 Sacred Geometry and Freemasonry
2:06:58 Difference between modern and ancient architecture, "textbooks in stone"
2:08:48 What is the Masonic Order, "secrets of Freemasons", Masonic traditions
2:12:30 Freemasons as custodians of ancient symbolism, Noah's ark, acacia tree, DMT
2:16:15 DMT as a boon to mankind and the mistake of criminalising it
2:21:34 Climatic optimum after population crash/ Ice Age
2:25:14 Climate shifts again into neo-glaciation, 6000yrs ago
2:27:40 Traumatic effect on consciousness as result of surviving near-extinction event, perhaps gene-deep
2:29:44 insert ''aliens'' meme
2:30:26 Responds hypothetically by calling back to the "7000 generations of modern humans" point and potential advancements of past civilisations, kicks off from there
2:37:58 Freedom to innovate stifled by bureaucracy, encumbering creative processes
2:40:39 Resistance motivates action
2:42:32 parable about making your own way
2:44:05 Why the name "Sacred Geometry"
2:44:56 Architecture, geometry, of our solar system is in perfect balance to allow for us to exist; Jupiter, Saturn, Uranus and Neptune via bucket mechanism deliver Panspermia to Earth
2:50:02 (Hypothetical) New Jerusalem as representation of our solar system, furlongs, horse racing, 7920, miles, numbers math my brain
