Depends on what you want.  If you want to convert them, then read up. Order some books on the subject and read them thoroughly.  Leave them lying around in prominent places. Keep it civil, though, even if they don't.  After all, they're family, and you have to live with them if you're not going to be moving away.

Or you could just talk to them.  Just tell them that you're not comfortable discussing religion with them anymore, and you'd like to let the subject drop.  You won't try to deconvert them so long as they keep their irrational beliefs to themselves.

Edit: If you go the second route, make sure you have something to back up your polite request.  If they're just insistent on saving your soul, you will probably have to do something a little more drastic.  Like plastering their vehicles with Darwin fish or something.

Cut to the chase, tell them they are god, just as you are, with a smile ....

As cool Alan Watts wrote: "The religion of Jesus was that he knew he was a son of God, and the phrase "son of " means "of the nature of," so that a son of God is an individual who realizes that he is, and always has been, one with God. "I and the Father are one." .......... and,  "Let this mind be in you." that is to say, let the same kind of [rational] consciousness be in you that was in Jesus Christ. Jesus Christ knew he was God." [ you and all are christ too ]

"Wake up" [said a buddha] and find out eventually who you also really are [ god ]. In our culture of course, they'll say you're crazy or you're blasphemous, and they'll either put you in jail or in the nut house (which is the same thing). But if you wake up in India and tell your friends and relations, "My goodness, I've just discovered that I'm God," they'll laugh and say, "Oh, congratulations, at last you found out." ~ Alan Watts

Hi. Thanks for your reply. They know I'm the one who questions things (life in general) the most - bar none. By abandoning my family, I mean not communicating w/ them again.

As far as repercussions go, yes. For example, my dad (especially) has threatened me w/ "if you reject God & the bible, we'll pretty much disown you as our son".

I'm fairly sure they're aware of the fact that the gospel accounts were not recorded until circa 65 CE. They just can't stand it when I bring up things that challenge their faith. They probably just want the 'fantasy island' belief to never fade away - who knows?

As far as evolution, they probably think it's possible. They're not trying to refute that, but I think they do try to refute "dangerous philosophical questions" that might 'lead them astray'. They think all of my internet inquiry is "dangerous to my eternal soul".

Thanks for the advice. I'll have to try that one.

Freethinker. This is largely why I don't go the, "I reject god route", and instead say I reject the way people and traditional religion interprets the ancient bibles. I will say all is simply gawed and no religion has explained it, and that science is how I prefer to study gawed.

This helps me side track silly arguing with the religious. I might also say, that jesus seems a good but minunderstood dude, but I will accept no idol of worship.

Since it looks like you're enjoying the scientific aspects of questioning, I would stick with that.

It also keeps the conversation from delving into the social aspects of religiosity, which can be quite emotionally heated at times. (i.e. choice, euthanasia, education)

There is always my favorite example of the flu shot. Did the parents or grandparents get flu shots? Why do they have to get new ones every year? Does god create a million new strains of influenza each year or does the virus mutate with the less survivable strains being naturally deselected?
