So if you have done any science/religion apologetics at all, you have heard something like the post below or this comment. "If the earth were only such and such closer to the sun then we would burn up, and if we were only such and such farther away we would freeze, another proof of God." Although awe-inspiring, I don't think that is good enough for the mature Christian to build his or her faith upon. I think you just might meet someone who has a few other questions about this "Set-up job by a Perfect and Loving God"
Here is just one of many questions for you to throw around this week that you might hear from an Atheist about this kind of faith/science statement.
"So what about Skin Cancer? For a perfectly positioned planet, that doesn't seem to be that perfect. Ice Ages? Global Warming?"
