<human>: Can you give me a shortened version of the text?

I am an atheist attending my state's university.  At the start of the year I got a knock from two Jehovahs' Witnesses and we had a good conversation.  They have been coming periodically throughout the school year, and I would venture to say we have become friends.

I have always been very honest with them in that I am interested in learning about the Bible but believe very little of what is written in it.  I told them I am an engineering student and very science-oriented.  They don't know, however, that I've gone full atheist.  They like my honesty, and have decided to keep coming back to talk and bring me pamphlets and other reading materials which they believe could resonate with a scientist.

My question is, now that we are friends, since they have no problems sharing their point of view, how can I attempt to make them see things from my point of view?  I don't want to be a dick, I don't want to belittle them, I want to do something that could potentially change the way they view the universe.
<bot>: Now that I have made friends with two Jehovah's Witnesses, what are some respectful ways in which I can get them to see things from a different point of view?
