When we stop and think about what the evolution worldview is doing, it is really simple.
They are arranging fossils in an order that makes them look like a sequence.
That is no different than if I line up a series of rings from small to large to say that one evolved from the other.
I can come up with all kinds of reasons to support my theory too! I can reason that based on shape, color, size, even chemical makeup, all of which would make sense if I already believe that one evolved from the other.
I would be looking for proof to support my theory instead of looking at facts and drawing conclusions.
In an evolutionist’s mind, evolution is already true—not because the evidence supports it, but because it is what they want to believe.
