Is Babylon AD a comick book?

No, "Babylon AD" is not a comic book. It is a science fiction novel written by Maurice G. Dantec and published in 1998.

There was a 2008 film adaptation of the book starring Vin Diesel, which was titled simply "Babylon A.D."

However, it's possible that you're thinking of something else, as the title "Babylon AD" has been used in other media:

* Babylon AD: The Graphic Novel, based on the film adaptation.

* Babylon A.D. (video game), a video game adaptation of the film.
