An Issue with Jesus' Parables?

Today a fellow named Tom Short and his ministry came by Purdue and basically did a Q&A on Christianity. During this time of five or six hours, one of the observers brought up a point. He stated that Jesus' parables were just redactions of Greek myth. Or perhaps of mythology in general, his phrasing was vague. This made me think for a moment: What's the point?

Indeed, what does that accusation accomplish? As someone who's dabbled in logic and is becoming a teacher, I don't see how this claim doesn't seem to harm Christ's message or Christianity as a whole. First remember the cultural context. By being culturally sensitive and using familiar stories, Christ made His work more relatable. This is a simple tool used in teaching; we take something students are familiar with and frame the new material within it.

Logically, this neither confirms nor denies Christ's existence, His work, or the Bible. You know, as someone who was an intellectual and not a true believer for awhile, I almost didn't include this. But then it hit me: in many cases, a complaint like this is exactly what it sounds like, a nitpick.

There are legitimate skeptical questions. How do we know the Bible is accurate? Where does it come from? Is it historically accurate? Sometimes it doesn't even take a Christian to see when a skeptic has a legitimate question or simply a  complaint, as I've shown above.
