They believed in Zeus or Odin and their creation stories. Or thought that the world was flat and carried around on a giant turtle flying through space. What makes Christians, Jews, and Muslims so sure they got it right this time when so many others were "wrong" and eventually faded from existence once another more attractive religion came along? Not to mention that since it happened before, it'll surely happen again and that Christianity, Judaism, and Islam will be replaced with something else.
