I am free to believe what I want and so are you, but the reason its not taught in biology class is it has nothing to do with human biology.
You're a hypocrite. You think people should be free to believe in the "virgin birth" but not free to believe in the events of Genesis 1-11. No biology class teaches that the "virgin birth" never happened, but every biology class teaches that the events of Genesis 1-11 didn't happen. As you well know.
But you're missing the point: the whole notion of "science" as representing "reality" and "faith" representing man's "ultimate questions" via profound but man-created "allegories" is mistaken. G-d is the Ultimate Source of Truth, not a "santa claus" who spews harmless little platitudes as a "symbol" of some kind. But so long as conservatives defend "religious freedom" (ie, that there really is no one true religion and that we're all just groping) this split is going to be with us.
You chrstians believe that G-d could (chas vechalilah!) set aside the unalterable rules of nature to produce a male human child without male seed, yet you turn right around and claim that G-d absolutely could not have created a fully completed world in an instant and then set it in motion.
Par for the course.
