Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Believe it or not, no aliens were likely involved! Just some very smart humans and a massive amount of labor.

You'd have a point if the Egyptians didn't already tell us how they moved giant, heavy things over land.

Lots of human labor.

Yes. I'm familiar with this image. Some scientists claim that when just the right amount of water is poured over sand it reduces the friction by about 30%.

Some also claim that there were not hundreds of thousands of laborers at the Giza pyramids, based on evidence discovered in the work camps near the site.

I'm 38 years old and I think I've read about a new theory every year of my life...

Who are these "some scientists?" Names please.

I'd suggest arguing against what they literally showed us they did is an uphill battle.

"The study was done by Christian Wagner and colleagues at Saarland University in Germany, along with researchers in the Netherlands, Iran and France. The team was inspired by an ancient Egyptian wall painting showing a huge statue being hauled across the sand on a sledge in about 1800 BC. The painting has a detail that has long puzzled Egyptologists: a worker who appears to be pouring water onto the sand in front of the sledge while others appear to be carrying water to replenish his supply."

There are hundreds of articles about this theory. It was all the rage a few years ago.

You grease up a sled and drag it down a track carved into some rocks.

Even with the wrong amount of water, sticktion is just proportional to weight. With enough force you can overcome any amount of it.

How many horsepower is that? Also, what is a horse? (bronze age Egypt joke)
