Yes, boundary fossils are used to create imaginary timelines, so that earth history can be better understood. Does finding a boundary fossil outside their previously-believed range invalidate the timeline...no, it just increases that organism's life range. So what if new timelines are made. That's just science reacting to a change of the "evidence" in the rock record. Is it a perfect system? No. Is it a reliable method that considers all the evidence fairly, and reaches a logical, reliable conclusion? Yes.
What's So Hard to Understand?
That's what we call science...something familiar to a scientist, but for some unknown reason it is a hard concept to grasp for a young-earth scientist. When new discoveries are made, theories change, textbooks re-written, research articles published. It is a great process.
Why do young-earth scientists like to disavow scientific methods? Mud-slinging, mis-statements, and controversies over ages which are taken out of context are all the weapons that a young-earth scientist has left, because they can't prove a young earth from science.
The author claims, "Creationists, including myself, have provided a variety of alternative explanations for fossil succession." Have they been accepted by the scientific community...NO, because there are no facts to back them up from the geologic record. They are only accepted within the small community of young-earth scientists, and their devoted followers. They say the world scoffs at them, because the Bible says they will be persecuted for holding to their faith...no, that's not true. The world scoffs because they hold to an unprovable, unbelievable theory based on an inaccurate interpretation of the Bible and science.
The God of the Bible is real, and yes, the earth is old. God's creation testifies to this. The Bible says, "speak to the earth, and it will teach thee" (Job 12:8). Let?s all listen to what the earth has to say.
The author assumes that the fossil record is becoming more random, and will eventually prove the flood. Unfortunately for him, this is far from the truth. Randomness will never be proved. In fact, the rock record has already disproved it.
