That is like saying if chickens evolved from dinosaurs, why don't we see dinosaurs anymore? Or why don't we see pseudo half bird, half dinosaur? <Oh yeah... hmmm... we do in fossil records>
Or saying if elephant evolved from Wooly Mammoths, why aren't wooly mammoths around today. :roll:
Putting your faith in the Creation story doesn't neccessarily have to make you ignorant of the facts. Plus, evolution doesn't neccessarily go against the Bible. It is just hermeneutics.
