Hm, if we're going to consider religion as modern myths and legends, I don't diss anyone that does and actually some things I believed are true since I studied a little bit of Christianity, Judaism, and Muslim at university. For the most part those religions aren't for me, so some of the stories in those three religions that are a bit too real to believe to me (again, not trying to diss the religions or anything). However, I studied the religions in a historical context, so those stories most likely are from real events one way or another.
As for Greek myths and legends, those are far more farfetched than the stories from today's well known religions, but I like to think those events are somehow related to real events one way or another like religion.
