Ecclesiastes 1:9
History merely repeats itself. It has all been done before. Nothing under the sun is truly new.

I can think of several things that refute that claim.
First flight by humans, first transatlantic flight, first flight around the world, first flight outside the world, first landing on the moon by man, first long distance communication via telegraph, first long distance communication via telephone, first close up views of Mars.
You get the picture, and there are literally millions of more examples. There will even be new firsts created in the future.
AFAIK, the United States Constitution is brand new under the sun, had never been done before, and changed history.
