Cool stuff.

But when did people learn the art of riding? This question and analysis has always been uneasy. There is evidence of horse domestication as early as two millennia B.C., but “breeding horses” does not mean “riding.” Most likely, the most ancient horse breeders bread them as a status symbol.

I am 100% certain that people were riding them from an early age but without stirrups chariots could be more efficient in battle.

But i bet they rode them as we race anything we can.

I know riding horses (and using dogs) has been very normal for ages in civilisation and therefore humans can't see it for what it is. Here I give the alien 'outside' perspective:

Take another (baby) mammal from their herd and not for food. Abuse it; control it by force and sit on it, enslave it. Furthermore: Set aside the natural selection process and 'breed' it into something humans prefer because civilisation humans think they know better than nature.
The San Tribes don't ride horses or use dogs

This is a good example of SUPREMACY over other lifeforms.

Take a look at how living nature is doing under our continuing violent domination and control? Are we still sure we know best?
mass extinction and ecosystems collapse

Perhaps domination/supremacy was a wrong idea in hindsight seeing how far it has come now and what's left of
Earth's living nature? Please consider that supremacy is really making insane. It is high time, and still not too late, to change our view on all other lifeforms.

Do you think that humans really are the supreme lifeform such as is deeply embedded in civilisation?
The answer to above question has humongous consequences.

Mystery Solved: Scientists Trace Source of Stonehenge Boulders
https://phys.org/news/2020-07-mystery-stonehenge-iconic-boulders.html

A study published Wednesday found that most of the giant stones—known as sarsens—seem to share a common origin 25 kilometers (16 miles) away in West Woods, an area that teemed with prehistoric activity.

The finding boosts the theory that the megaliths were brought to Stonehenge about the same time: around 2,500 BCE, the monument's second phase of construction, which in turn could be a sign its builders were from a highly organized society.



... Lead author David Nash, a professor of physical geography at the University of Brighton, told AFP he and his team had to devise a novel technique to analyze the sarsens, that stand up to nine meters tall (30 feet) and weigh as much as 30 metric tons.

They first used portable x-rays to analyze the chemical composition of the rocks, which are 99 percent silica but contain traces of several other elements.

"That showed us that most of the stones have a common chemistry, which led us to identify that we're looking for one main source here," said Nash.

Next, they examined two core samples from one of the stones that were obtained during restoration work in 1958 but which then went missing until resurfacing in 2018 and 2019, respectively.

They performed a more sophisticated analysis on these samples using a mass spectrometry device, which detects a bigger range of elements at a higher precision.

The resulting signature was then compared to 20 possible source sites for these sedimentary rocks, with West Woods, Wiltshire found to be the closest match.



Only the 17th century English natural philosopher John Aubrey had previously postulated a link between "Overton Wood," probably a former name for West Woods, and Stonehenge.

Previous work has found that Stonehenge's smaller "bluestones" came from Wales, about 200 kilometers (160 miles) to the west, and the new study says that they and the sarsens were placed at the same time



Just how the early Britons were able to transport the boulders weighing up to 30 tons a distance of 25 kilometers remains unknown—though the prevailing idea is they were dragged along sleds. The site's significance also remains mysterious.
