Faith, how would you explain why no crab fossil has ever been found among trilobite fossils? Or, why has no trilobite fossil been found among crab fossils? Trilobites and crabs both are kind of, you know, seafloor critters. Did they not like each other? Do floods wash them to different places because, maybe, crab claws get caught up by currents?
Why is that?
"The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken
