Because I truly believe evolutionists are stupid and ignore the evidence before them.
Why don't you actually refute something instead of just calling creationists stupid for a change.
FR's geologists do a far better job explaining the difference between the layers at Mt. St. Helens and the layers in the Grand Canyon. However, just for starters, how do you account for the fossilized rain drop patterns found halfway through the columns? Or the fossilized animal burrows, or fossilized animal footprints, etc.? You cannot, but it won't matter because you'll come back with the same benighted crap on the next thread completely oblivious to all that has gone on before.
Oh well, I hold out greater hope for the intelligence of the lurkers.
