How come horses were so common all over the world in the past

Question

I recently watched a documentary about a brief history of each continent when I noticed horses were really common everywhere for an example Genghis khan in Asia, Saladin in Africa, natives in North and South America and all over Europe too. I know they’ve been brought with settlers to Australia because it was mentioned in the documentary but what about the other continents ?

Answer 1

I think their prevalence is because they were incredibly useful to our ancestors so they brought them with them everything they went.

As a side note, horses aren’t native to North America. I found this hard to believe cause I’d always seen images of native Americans riding horses but truth is they got the horses from white settlers.
