I would have given you a positive rating if I could, lol. Thanks a lot for the material bro. In particular in those COVID-19 times and with the Ramadan around.
Yes, the Arabian Peninsula, is a treasure trove for the study of the earliest human migrations and prehistory and ancient history (established history) given its historical richness, existing known ancient civilizations and pre-historic cultures, geographic location, climatic abundance of (not many millennia again most of Arabia was extremely fertile and home to some of the largest lakes and rivers in the world - in fact the 100's of wadis in KSA and Arabia - wadi can be translated as dried out rivers that only spring to live in case of rainfall or occasionally each year) are a testament of as seen on that map from the BBC article.
At the same time, Arabia, even to this day, is a largely undiscovered area for archeologists. In particular KSA was largely closed off in recent times, did not prevent many visitors, in particular Westerners, from collecting 1000's of ancient artifacts.

BTW for those interested, I can highly recommend the work of Prof Michael Petraglia, who is the professor of human evolution and prehistory at the School of Archaeology, Oxford University. He used to have (I think he still has) a very interesting Twitter profile with much focus on Arabia and Horn of Africa (Ethiopia - apparently where humanity first originated many years ago).

Since we are on a Pakistani forum, I have always had an interest in the relationship of ancient civilizations in what is modern-day Eastern Arabia and Southern Iraq (basically the Eastern part of the Arab world) and IVC which is actually a rather deep bond. Primarily Dilmun, Magan, Sumer and IVC.

Dilmun, one of most important ancient civilisations of the region and said to date to the third millennium BC, was a hub on a major trading route between Mesopotamia - the world's oldest civilisation - and the Indus Valley in South Asia.
It is also believed that Dilmun had commercial ties with ancient sites at Elam in Oman, Alba in Syria and Haittan in Turkey.
I think that the mighty Rub' al-Khali desert might have quite a lot of surprises given its geological history as well, personally, but this is also based on some scholarly work. How/when/if that will ever be confirmed by any findings is more difficult to tell given the inhospitable geography and enormous size.
For the very same reason (pre-history and general curiosity about the history of mankind) I have always had an interest in Ethiopia and the Horn of Africa as well.
