Not true.
Islam (and related two religions) date back to the creation of Adam.
Rest of the part is completely false imagination and hope of yours. Which you might be entitled to.
It is your belief that makes you feel like that. Historians ascribe the birth of the Islamic faith with Prophet Muhammad. You can predate it as many thousands of years you want, but the truth is like Christianity started with Christ, Sikhism started with Nanak, Buddhism with Buddha, Islam started with Prophet. Islam is the youngest of all the major religions in the world.
