Evaluating some common evidences for long ages

In Bible class, we learned that scientific evidence does NOT speak for itself but must be interpreted. And scientists--the folks who do the interpreting--are just regular people with biases that can be wrong. So we need to be careful what we believe. Lately, we've been considering some well known evidences that "prove" that earth is billions of years old. The geologic column is one such evidence. The many layers with their fossils have been associated with the evolution of life over millions of years. We learned that the complete geologic column does not actually exist anywhere in the world. It's a theoretical compilation of layers located in different places. Also there are many problems with thinking the layers formed slowly (which supports the idea of vast ages). Unconformities (missing layers, lack of inter-layer erosion, polystrate fossils) and exteme folding are riddles that don't fit the long ages interpretation. The common interpretation is that geological layers and fossils show the sequence of life over millions of years. Here is another interpretation that, I think, fits the evidence way better: the layers and fossils show that sequence of death during the global flood as different environments were impacted. As water rose during the flood, Low lying marine environments were hit first; higher ground and animals that were mobile wereaffected later. Next we'll learn about radio metric dating, ape-men, and distant starlight.
