Note that the Creationists not only are anti-geology and anti-biology (and anti-physics and anti-chemistry), they even fail at simple mathematics.
We're witnessing another of those funny dances one has to see to believe. This is ID in action, folks!
If you are referring to myself, fine. I was never good at math. But like your friend who ascribes "disgrace to humanity" to someone who accidentally misquotes a word, you have made a sweeping judgment based upon a very small sample, and math ain't got squat to do with that until one realizes how grossly innaccurate are your words.
Meanwhile, have you done the math yet? How much of the earth has been exposed for scientific observation and analysis? If it does not matter how much of the earth has been sampled, then why refrain from boldly proclaiming the percentage?
