The same old stupid claim remade,first of all there is textual and archaeological proofs of Mecca from Infact even before 4th century
https://discover-the-truth.com/2013/09/03/did-kabah-in-makkah-exist-before-4th-century/As for your second one there is proof it was a trade route,in those times
Claudius Ptolemy was a Greco-Roman writer of Alexandria, known as a mathematician, astronomer, geographer; is another person, centuries before Islam who makes mention of Makkah. He uses the name ‘Makoraba’ for Makkah.
In the Book: ‘The New Encyclopedia of Islam’, written by Cyril Glassé says that Ptolmey, in the second century mentioned Makkah. Here is what he wrote,
“Mecca (Makkah al-Mukarramah, lit ‘Mecca the blessed’). For thousands of years Mecca has been a spiritual center. Ptolemy, the second century Greek geographer, mentioned Mecca, calling it ‘Makoraba’. Some have interpreted this to mean temple (from Maqribah in south Arabian) but it may also mean ‘Mecca of the Arabs’.” [5]
Ilya Pavlovich Petrushevsky (1898–1977) was an Professor of History of the Near East at the University of Leningrad for twenty years, he also makes mention that Ptolemy in the second Century mentioned Makkah:
“On the caravan route from Syria to the Yemen, in the Hijaz neighbourhood, lay Mecca. Ptolemy, the Greek geographer, mentions it as early as the second century calling it Makoraba, which is derived from the south Arab word Maqrab meaning ‘sanctuary’. [6]
It was a trade route between Syria and Yemen and this is a historian speaking,not some average Muslim.
Infact let me quote a Christian saying it existed in the time of Patriarchs which was very ancient,btw
Reverend Charles Augustus Goodrich a Christian, was an American author and Congregational minister comments on Kaaba and Mecca, although, he is not fond of the Prophet Muhammed (pbuh), but he is sincere in admitting that Ka’bah existed at the time of Patriarchs. He writes:
“Among the variety of fabulous traditions which have been propagated by the followers of Mahomet, concerning the origin of this building, we find it asserted, that its existence is coeval with our parents, and that it was built by Adam, after his expulsion from paradise, from a representation of the celestial temple, which the almighty let down from heaven in curtains of light and placed in Mecca, perpendicular under the original. To this the patriarch was commanded to turn his face when he prayed, and to compass it by way of devotion, as the angels did the heavenly one. After the destruction of this temple by the deluge, it was rebuilt by Abraham and his son Ishmael on the same spot, and after the same model, according to directions, which they received by revelation; and since that time, it has continued to be the object of veneration to Ishmael’s descendants. Whatever discredit we may give to these, and other ravings of the Moslem imposter concerning the Caaba its high antiquity cannot be disputed; and the most probable account is, that it was built and used for religious purposes by some of the early patriarchs; and after the introduction of idols, it came to be appropriated to the reception of the pagan divinities. Diodorus Siculus, in his description of the cost of the Red Sea, mentions this temple as being, in his time, held in great veneration by all Arabians; and Pocoke informs us, that the linen or silken veil, with which it is covered, was first offered by a pious King of the Hamyarites, seven hundred years before the time of Mahomet.” [1]
Also,as for Al-Lāt,Al Uzza and Manat,Read Ibn Kalbi book of Idols, it proves in Mecca there were these idols,Infact it proved your whole argument wrong,Mecca did exist,it was a trade route,and it was a place of worship for the pagans before Muslims, and in conclusion your argument has been destroyed.
