Creationists keep saying this, but they've never given any evidence to support this contention. I suppose you have a few scientific studies to back your claim? Note the key words: as taught to me as fact in junior high
The peppered moth story was taught as fact. That dinosaurs were cold-blooded reptiles was taught as fact. That life began when chemicals in the ocean reacted to cosmic rays was taught as fact.
These things have been discredited or at least called into significant doubt.
And add all the pop psycho-babble -- unreleated to evolution -- taught as science fact, along with the prohibtions on prayer and Bible readings, one can conclude that that our educational authorities are more interested in descrediting Christianity than in imparting knowledge.
Are you sure they said "this is a fact" and not "this is current scientific reasoning?" I went to junior high a quarter century ago, and while I'm fuzzy on the details I'm pretty sure none of my science teachers ever said anything was set in stone. As additional data points come in theories are refined. If your science teachers did not tell you this then they were in error. Of course, I may have had a leg up as I attended a magnet program where the teachers were a cut above the average.
