“But like I said, it’s a theory...It sure would help explain a lot of things...”
Yes, I think that’s important to keep in mind. There may be suggestions of these things in the Bible, but I haven’t really seen enough clear cut evidence to say that, for example, dinosaurs existed only before the current creation. It may be a useful theory to explain some things we observe in nature, but then again it raises other questions.
For example, if corporeal life begins in the 6 day creation, then we can assume all fossils have arisen since then, and we have a concrete timeline to work with as we attempt to explain that physical evidence. However, if we do not know when the first animals lived on earth, then we don’t know when the first fossils originated. Instead of assuming much of the fossil record was laid down in Noah’s flood, we would have to admit that the layers from Noah’s flood could be located much higher in the geological column.
And then God says He created pretty much everything except humans after it’s own kind...An indicator of two things...One, that these things existed before the creation as we know it and two, evolution is entirely out of the question...
