Let us briefly discuss the nature of the Semitic religion as hypothesized by Ditlef Nielsen around 100 years ago, whose triadic hypothesis of Father-Moon, Mother-Sun and Son-Venus, although rejected by modern scholarship, still holds popular appeal. The old Arabian religion was the mother of the other Semitic religions and it was composed of the astral triad of Sun-Moon-Venus.This triad corresponded to Father-god, Mother-goddess and divine Son, respectively.Our knowledge of Sheba and its patron god Ilmaqah comes from these archaeological expeditions and excavations conducted in the last 150 years.Clearly, "everyone" could not have known that allegedly being a Moon-god, it does not appear in the scholarly literature until the beginning of 20th century.Both the Hebrew Bible and the Qur'an place Solomon and the Queen of Sheba as contemporaries.
Solomon was also told that the Queen and her subjects worshipped the Sun.
However, according to the Christian missionaries "archaeology" has shown that Sun-worship by the people of Sheba was "proven" to be incorrect since Moon-worship was prevalent in this particular region.
In order to support their supposition they relied on an article called A measure of Muhammad's limited knowledge of the ancient traditions of the Arab deities is gained from the fact that the Qur'an states that the Queen of Sheba was converted to the true god from the sun-worship of her people (Pritchard 1974 14), while all the evidence at Marib suggests that the Moon God, the very source of the crescent of Islam, was always the predominant deity.
Recently, another missionary came up with a similar claim which he made by assembling bits and pieces of material off the internet which he subsequently labelled as "archaeological evidence".
It is surprising that the above two articles, which claim to represent "archaeology" do not provide any scholarly reference(s) as to where exactly the evidence from Marib suggests that the Moon-god was always the "predominant deity" during the time of the Queen of Sheba.
