 And if Christians are making the case for their own worldview, some other worldview will fill the vacuum. Well, what do we do with that then, the potential effect on the Christian worldview? My audience knows, and I've had this discussion with them before, I don't believe there's life on other planets. If there was life on other planets, it would require God to create life. So when people say, well, with all the vastness of the universe, there has to be other life, that's irrelevant if it takes God to create life.
