All false religion began in ancient Sumer with Nimrod. All archaeologists now agree that the first civilization was in the Fertile Crescent particularly at Shinar, where is Shinar? Shinar is the Biblical name for Iraq,
Allah is AL-ILAH, which is related to Enlil, Baal, Baili, and to many other false gods. So Allah contrary to popular belief was not invented by Muhammad the Muslim prophet but in fact existed before his birth. Muhammad's father's name was Abdullah, abd in the Arabic language can refer to a slave/servant therefore Abdullah means servant of Allah. In an allegory, a poem was written centred on Gilgamesh, this is another name for Nimrod. The goddess is addressed and scolded for trying to kill Gilgamesh
The pre-Islamic Arabs believed in a host of other terms to signify gods, such as Hubal and al-Lāt, al-`Uzzah, and Manah. Pre-Islamic Jews referred to their supreme creator as Yahweh (Jehovah) or Elohim.

Allah's root is is LIL, shortened to IL from Enlil. So Allah really evolved from Enlil to Lil and then IL. Remember the name used in the Bible Baal, is the Hebrew Ba'il meaning "the god", in Arabic it would be Al-Ilah and in Aramaic Alaha.
There is an inscription in stone from Al-Ula in Northern Arabia, circa 500 BC, just 1000 years before Muhammad was born. In the same Semitic language dialect, and in the same time frame, are two other names of the gods- Mar-Allah, meaning Lord-god, and Adar'IL, a Sardonic contraction using the root form of the name for god from Sumer, LIL.
The god allah was exported by Nabonidus into Northern Arabia in the 6th century BC.
At the time of Muhammad Allah was the chief god with three daughters Allat, Manat and Al-Uzza. Manat seems to be worshipped in Saudi Arabia earlier then Al-Uzza and Allat. You can read about these three daughters of Allah in Sura 53.19-20
It may be interesting for you to know that Muhammad in the early Meccan period never spoke about Abraham or the God of Abraham Yahweh. Muslims in desperation try to point out that Abraham is mentioned during the Meccan period but the Suras they present as evidence are disputed to be later Suras revealed in Medina.
It may come as a surprise to the listeners that it was Nimrod who was deified and later became Molech, Baal and Allah, it was often the custom of pagans to kiss their deities statues thus we read in the Bible
Allah can be found in the Bible in 2 Chronicles 26:7 And God helped him against the Philistines, and against the Arabians that dwelt in Gurbaal, and the Mehunims.
Notice Gur-Baal is the name of the city named after the deity of Allah.
It will be astonishing to learn that a reference to a King Vikramadity inscription was found in the Ka'ba temple in Mecca, proving beyond doubt that the Arabian peninsula formed a part of his Indian Empire", so it is quite possible that this was indeed a Hindu Temple as you know Hindus worship many deities and the Ka'ba pre-Muhammad's time did house at least 360 deities.

"The text of the crucial Vikramaditya inscription, found inscribed on a gold dish hung inside the Kaaba shrine in Mecca, is found recorded on page 315 of a volume known as "Sayar-ul-Okul" treasured in the Makhtab-e-sultania (library) in Istanbul, Turkey." (IBID)
It might come as a stunning revelation to many that the word "ALLAH" could possibly be derived from the Sanskrit language. In Sanskrit Allah, Akka and Amba are synonyms. They signify a goddess. The term Allah forms part of Sanskrit chants invoking goddess Durga, also known as Bhavani, Chandi and Mahishasuramardini. The Islamic word Allah for God is therefore could possibly be ancient Sanskrit appellation retained and continued by Islam. The word Allah could mean in ancient sanskrit mother goddess." (IBID)
Also, there are inscriptions found near oases, Allah and Allat appear with no descriptive attachments, either in appeals for help in travel, or as part of the signature of the suppliant (like Abdallah-- IL root in name!). What does this mean? This means that IL and Allah shared the reverence of the ancient Sumerians, circa 3000 BC, and the northern Arab tribes in 500 BC. Survival time-- 2500 years. (Winnett, F V, and Reed, W L, Ancient Records From North Arabia, Univ. of Toronto, 1970 pg. 79,126-127 / 245,253b. Winnett has done some excellent work in recent work in inscription interpretation.)
Muhammad did indeed cleaned the Ka'ba of several gods but took the god allah for the choice of worshipping him. This in itself is the concept of not only creating a religion but a god that does not actually exist.
Muslim pilgrims visiting the Ka'ba temple go around it seven times. This custom is not preserved in any Mosque. Hindus also circum-ambulate around their deities. This is yet another proof that the Ka'ba shrine could be a pre-Islamic Indian Shiva temple where the Hindu practise of circumambulation is still meticulously observed.
