People usually use this philosophy to defend their beliefs in aliens. We have no idea how big the universe is, because God is amazing and i believe that the universe was made for us to explore and discover new things, ideas, and inventions. Just because the univrse is big doesn't mean that there are aliens. If there were aliens, it would've said that God made them in the Bible. The bible says, "God made the heavens, and the earth" heavens meaning the universe, but earth meaning: the only special little tiny planet that's inhabitible. If there were aliens, the Bible would've said "God made the heavens, the Earth, and mars." or something like that.
