           | 
           | I think this is a common misunderstanding.
           | 
           | Yes, there are some who think aliens built the pyramids.
           | 
           | But there is an equally large group of people who think that
           | humans pre-ice age were advanced like we are today. And when
           | the ice age happened 12,000 years ago - that knowledge was
           | lost.
           | 
           | When you then look at build sites around the world from this
           | perceptive, structures like the Sphinx and others (like
           | Gobekli Tepe), begin to appear much older than convention
           | teachings might imply.

             | "Advanced" can mean a couple of different things. I think

             | reason", and that's _much_ more interesting to think about!
             | 
             | I think there's a tendency in the modern perspective to
             | equate technological advancement with intelligence, and so
             | we (laypeople and dilletantes especially) tend to think of
             | these long-ago cultures as being sort of comprised of
             | primitive _people_ because they built primitive _things_ ,
             | by modern standards. Writing systems, technology, politics
             | & governance, math, chemistry, mechanical systems,
             | metallurgy and materials science, medicine -- minor
             | periodic and localized variations aside, all of these were
             | pretty darn primitive, near as we can tell, and so the
             | people must have been, too.
             | 
             | But maybe advanced people do primitive things because the
             | process of developing technology takes a long time. Think
             | about everything that's required to reliably produce steel;
             | maybe a prerequisite for steel is 10,000 years of
             | agriculture.
             | 
             | The "Primitive Technology" channel on YouTube is a great
             | case study. We have an individual who has access to modern
             | knowledge and technology, but re-producing it is
             | extraordinarily laborious and he's still in the mud hut
             | phase of development -- and he can escape that time period
             | at any time to get access to modern medicine and a rich,
             | nutrient-dense diet.
             | 
             | I think this might be a strong argument against ancient
             | technologically advanced civilizations (and alien
             | claptrap). It's unlikely that things really developed that
             | much out-of-order because it just takes too dang long to
             | develop all the steps between basic agriculture and powered
             | machinery. It's kind of like that counter-argument against
             | the "moon landing was a hoax" nutters: in 1969, we didn't
             | yet have the film technology required to fake a moon

             | didn't have the tools to do it, yet.
             |

             | Pyramids are a pile of big rocks. They're pretty well
             | fitted big rocks, but engineering and construction wise
             | they've got nothing on a Burj Khalifa, or a Millau Viaduct
             | (below which the Great Pyramid would fit handily), or a
             | Three Gorges Dam.
             | 
             | The Palace of the Parliament of Romania has a larger outer
             | volume than the Great Pyramid, and is ~40% lighter, and is
             | an actual building (so large it's mostly unused), and was
             | built in just 13 years, by Romania, in the 80s.
             | 
             | Hell, while the Memphis Pyramid and the Luxor Las Vegas are
             | smaller than the Great Pyramid, they're mostly usable
             | volume, not mostly rock.
             | 
             | It's not that we _can 't_ build a pyramid, it's that if you
             | have a few hundred mils lying around there are more useful
             | and / or cooler things to build.

             | First, GP claimed it couldn't be done even with machines.
             |

             | 
             | First, what work, building pyramids? Because people have
             | definitely built shit by hand in your lifetime, I can
             | assure you.
             | 
             | Second, why would we do things the slower, more expensive,
             | and more dangerous way, if we don't have to? You don't get
             | your nonsense delivered to your readers by runners, riders,
             | or messenger pigeons, that doesn't mean they didn't exist.
             | 
             | But if you want an example of human hard work in the modern
             | era, look no further than Dashrath Manjhi. Dude hammered
             | and chiseled his way through an entire ridge over more than
             | 20 years.
