Allow one assumption and you can prove anything to yourself. For instance, let’s assume that all the stories of evolutionism happened. So, all the stories of evolutionism happened. Therefore, all the stories of evolutionism happened. Oh, that’s too obvious. Let’s put some steps in there, some circular reasoning, and some infinite regression to hide the fact that we’re just making stuff up. btw, the same trick is done with theologies based on Bible verses plus assumption. All it takes is a single assumption and we have added to God’s words, whether God is speaking through the Bible, the Creation, personal leading, conscience, or through one of the other means mentioned in the Bible. For the deceptive and desperately wicked carnal mind, assumptions are a very natural way of thinking.
