Every religion was created by Allah

Every religion was created by Allah. In every generation, She chose one person to write and convey his words on his behalf. The Bible, the divine book of God, was recorded by people whom God chose. Although the Bible was spoken and written down by people, God is still the source of the words, the one and only author of the Bible, and the founder of true religion. No person can claim to be the founder of religion nor can anyone claim to be the author of the Bible. People can only write and speak on behalf of God.
For believers, hearing and reading the Holy Bible is the same as hearing and reading the words of God. All of today’s major religions have their own scriptures. It should not be. We should read others.
God [Elohim] created Adam as his own image which was not before and start the  era of prophet hood to develop mankind until they are perfect enough to be like Him and capable as Him.
According to my opinion Prophet Noah is the father of all religion and race. And then God is continuously experiment with His creation through sending the messengers in different status and power. One of the great example is Jesus Christ came through spiritual birth. Only he had no earthly father like Adam but only He got the status of son of God.
Universally, the prophets are many kinds - the Major Prophet and the Minor Prophet. Or one is the independent Prophets who are followed; the other kinds are not independent and are themselves followers. And many more types of Prophet we had and we have.
The independent Prophets are the lawgivers and the founders of a new cycle . . . The Manifestations of universal Prophet Hood Who appeared independently are, for example-

Krishna, Abraham, Buddha, Confucius, Zoroaster, Moses, Jesus Christ (Spiritually "The son of God") and Mohammed [The Seal of the Prophet Hood (It is true in every era there is a new manifestation of God. And every instant the Loved One assumes a new garment, now of age, now of youth .The Spirit has appeared in various forms as: Adam, Noah, Abraham, and Jesus. In every generation the Spirit was coming and going, until at last he appeared in Muhammad and ruled the world)]. 
The others who were followers and the promoters are like Solomon, David, Isaiah, Jeremiah and Ezekiel.

Among them only Jesus Christ is available for the service and coming again for the salvation of mankind.

And other types are the inheritor of the Prophet Hood like John the Baptist and Saint Paul (For Jesus Christ). 
Another types are the reformer like Bab, Baha’u’llah (Both the founder and the inheritor), Mirza Gulam Ahmed.  
Another type of Prophet is Rael (Only founder who introduced religion depending on science).
Thus it is that whatsoever be their utterance, whether it pertain to the realm of Divinity, Lordship, Prophet hood, Messenger ship, Guardianship, Apostleship, or Servitude, all is true, beyond the shadow of a doubt.
The independent Prophets are founders; they establish a new religion and make new creatures of men; they change the general morals, promote new customs and rules, and renew the cycle and the Law. Their appearance is like the season of spring, which arrays all earthly beings in a new garment, and gives them a new life. With regard to the second sort of Prophets who are followers, these also promote the Law of God, make known the Religion of God, and proclaim His word. Of themselves they have no power and might, except what they receive from the independent Prophets.
And the inheritor of the prophets represents himself as a prophet trough getting some new messages for mankind.
