ELI5: If there are no lions in Europe, why are they all over European heraldry?

Owls, bears, boars and all that make sense because Europeans would see them all the time.  I've never heard of lions indigenous to Europe, and yet lions are everywhere when you look at European heraldry.  How come?

modern europeans largely have a greek/roman lineage, to some degree (at least culturally).  romans had lions.  Lions are depicted in the bible.  Lions territory used to be quite large as well, living in southern europe.
