Actually what is now KSA has several ancient Christian sites. One of the oldest churches in the world was built in KSA (Eastern Province) and many early Christian (so-called saints) had their origin in what is now KSA.

Due to looking down upon anything pre-Islamic I am sure that there are many more treasures out there. We know very little so far.
Also quite a few archeologists say that Mount Sinai is located across the Red Sea in Northern Hijaz and not in nearby Sinai.
Christianity has a long history in KSA. Many famous pre-Islamic Arab figures were Christian too. Even to this day you can see Israel/Palestine with the barren eye from Northwestern KSA. (Hijaz)
Judaism, Christianity and Islam are Semitic religions. In other words those are our indigenous religions as Arabs and Semites. Non-natives who follow them should not speak in their name. Whether they are Indians or Romanians. Let's make that clear first.
60% of the world's population follow our ancient religions.
Christianity along with Judaism has a long history in the Arabian Peninsula.
Many Kingdoms on the Peninsula were either Christian or Jewish. Of course the retards on PDF have no clue about that and are polluting threads and meddling in Arab matters as usual.
Lastly there are hundreds of churches from Yemen to Kuwait and even temples. Almost every major city from Aden to Kuwait City has churches and now temples due to Hindu migration.
Yet there won't be any temples of churches in KSA as all natives are Muslim today and all the non-Muslims are guest workers or guests that are here to stay temporarily. They can pray at home.
I don't see Mongolia building Hindu temples or Latvia building mosques. Why? Because none of the natives follow those religions. Nor is African paganism practiced in KSA.
KSA is home to the most sacred Islamic places on earth. People don't seem to understand this simple fact.
A Muslim can pray anywhere. He does not need a mosque.
Lastly people in KSA don't give a crap about what outsiders think. They are holding steadfast to their ancient culture and traditions despite unlimited riches. Not comparable to anyone else on this front.
Which other people n the ME follow their indigenous religion, speak their indigenous language, use their indigenous names, dresses etc. to this very day to such an extent? The answer is nobody. Everyone has to an large extent been heavily influenced by outsiders on this front. Arabs the least of all people in the ME.
Arabs are basically the Romans of West Asia on this front.
