The issue is where the original Kaba was. Arheological evidence points towards Petra. Mecca of Hijaj yielded no archeological evidence of any major city prior to 7th century. Evidence is needed to back up the claims.
Makkah was a village inhabited by the quraysh there is very little left since huge skyscrapers hotels have been built and the original sites demolished concreted by the najdis they have destroyed whole mountains including safa and Marwa . It wasn't some super archelogical site since the houses were mud dwellings and dug out mudlike caves in the hillsides.
Makkah was a trading stop and place of pilgrimage it was built on trade by the quraysh crops came from madina taif yemen Syria even dates came from madina since nothing grows in makkah . And the outskirts were desert where the bedouin lived makkans would sent their children to be raised 100s miles away in the desert to grow strong and learn pure Arabic its there the bedouin lived a pastoral hunter warrior life and the tribes that then became Muslim, rasoolullah Foster tribe halima sadia whose milk he drank were the banu Saad. This tribe was north of makkah between madina where prophet lived and was raised by halima sadia and prophet was a shepherd before going back to makkah after his childhood.
You can see the original cave like mud houses above the library embedded in the hill side just above the library rasoullah saw house in makkah. There were trees there all that has been destroyed by Saudi goverment who razed all that area alongside any ottoman era buildings dwellings and earlier era during muslim ummayads abbasid.
Petra is called al raqim and is mentioned in the quran surah kahf it was a trading town on the caravan route to yemen through hejaz into Jordan Syria.
And the hejaz region went up all the way to the gulf of aqaba in the North to the borders of yemen what where najran meets yemen.
Gulf of aqaba is the hejaz including the city of al hijr the second city after petra for nabateans which is located in madina divsion these people were destroyed prior to rasoolullah saw ive given the hadith of rasoullah saw crossing these ruins tombs when they were on their expedition of tabuk against the Romans.
The New Saudi city of neom is geographically and historically being built in the region of hejaz near gulf of aqaba.
Since the quraysh were traders and in summers went to Syria and winters went to yemen I don't see what the problem is .
The historical Jewish sites villages farms like khaybar are in madina hejaz not petra.
There are many farm areas in hejaz like tabuk , madina, taif .
Historical ports in hejaz are yanbu and jeddah
Clear links of trade towards Africa.
Yanbu is in madina and is close to the battle of dhul ushayra where prophet led an army .
And jeddah is in makkah and historical sites have been found there and includes the tomb of eve bibi hawa since she landed from heaven in jeddah.
Also hazrat uthman the third caliph made jeddah the main port of makkah after transferring it from al shoaiba
Hazrat uthman was one of prophets companion and did not come 300 yrs afterwards
Proof they were living in makkah area .
And also authentuc hadith of the beached whale near yanbu coast and Sahaba bringing and eating its meat . This was part of the caravan raids by the Muslims against the qurayshi caravans of abu sufyan hugging the hejaz coast .
And the biggest proof of makkah being a trading stop and place of pilgrimage is surah fil and also the Wells of zam zam .
those gold coins or Old antiques were not minted by the Muslims they were acquired through trade and loot in wars . The Muslims also acquired Greek artifacts books libraries which later were translated and ideas studied and developed by Muslim scientists theologians later on in levant Iraq persia.
