Actually its older than all Abrahamic religions. It is hypothesized to be over 15,000 years old, well pre-dating recorded history.
It has been variously proposed that it began as a religious sacrifice, as an aid to hygiene where regular bathing was impractical, as a means of marking those of higher social status, as a means of humiliating enemies and slaves by symbolic castration, as a means of differentiating a circumcising group from their non-circumcising neighbors, as a means of discouraging masturbation or other socially proscribed sexual behaviors, as a means of removing "excess" pleasure etc.
There are many theories behind its origin and it ha been practiced in various societies for various reason,but it is obviously older than all Abrahamic religions
