Honostly, you cannot tell me that you have never heard this, or read any books during your years in school?
I never once heard of "Nebraska Man" until I became aware of the creationist movement about five years ago. I challenge you, Nothingness - heck, I double-dog-dare you - to find one single example of a non-creationist biology textbook published since 1930 that "teaches" Nebraska Man as anything other than a mistake. I very much doubt that you'll even find it mentioned at all.
Produce me a reference, or shut up about this "fraud." There was no fraud.
