Why Are Monarch Butterflies Afraid of the Truth?

Today I learned that when Monarch butterflies migrate south for the winter, all the ones that go across the middle of Lake Superior suddenly stopped going south and go west for five miles then continue south. This really freaked scientists out because like what is in the middle of Lake Superior? What do butterflies know that we don’t? Is this the end times, ? or is that where Loch Ness monster lives ? etc.. Anyways it turns out that about a hundred million years ago there was a mountain there and the butterflies still think they got to fly around it.  

Can’t they accept reality or are afraid of change ?  Don’t be afraid to face the truth Monarch butterflies just do it !!
