Also, a common misunderstanding is the conflation of evolution the theory with evolution the phenomena. When Einstein proved that Newton's theory of gravity was wrong, he obviously did not disprove gravity, but just Newton's explanation of it. Objects continued to fall when dropped.
Evolution, in the simple sense, is simply a fact. Life on Earth has changed over time. The fossil record, DNA evidence and direct observation all clearly demonstrate this.
*How* this happens is much more open. Darwin's theory of evolution by natural selection is deservedly the dominant "theory of evolution," but there have been others proposed over the centuries, such as Lemarckian evolution. These theories could be wrong, but even if Darwinian evolution was disproved tomorrow, we would lose an explanation but not the phenomenon it was trying to explain. Because life on earth still changes over time, and objects still fall when dropped.
