How long have Arabian horses been on earth?

While it's impossible to say for certain how long Arabian horses have been on Earth, the best estimates place their origins around 4,500 to 5,000 years ago in the Arabian Peninsula.

Here's why:

* Ancient Origins: Archaeological evidence and historical records from ancient civilizations like the Assyrians and Egyptians show the existence of horses resembling Arabian horses in that region.

* Fossil Record: Fossil evidence supports the theory that horses were present in the Arabian Peninsula even earlier, potentially as far back as 40,000 years ago. These early horses likely evolved into the modern Arabian breed over time.

* Genetic Studies: Modern genetic studies have shown that Arabian horses have a unique and distinct lineage that sets them apart from other horse breeds.

It's important to note that the exact origins and timeline of the Arabian horse are still being studied by scientists and historians. However, the evidence suggests that they have been a part of the human world for a very long time, contributing to the development of many other horse breeds throughout history.
