You need some glasses. Going off that whatever challenges science is a danger to society? If it's one thing any self respecting adult should have learned growing up it's that not all adults can be trusted. Being educated doesn't make it any better. Just look at the global warming loonies on both sides of the fence. Scientific findings can't and shouldn't be trusted blindly. Whether it be a scientific and or religious hypothesis I don't care, but something should always challenge science to find more proof.
The theory of evolution is certainly disputable. If it wasn't it would no longer be a simple theory.
The theory of gravity is debatable as well. Again it only makes sense in the way we know it now. There's nothing to say that won't change. Depending how far you pick it apart you could say in the future, should we discover those changes, that the theory of gravity exists and has only changed from what we thought it meant, or that the theory of gravity was completely wrong, a false premise of older age humans, and is now known as the theory gravitatamus. If it changes in the future, either way, we were wrong now, and the theory of gravity became disputable.
