I am going to make a more complete reply, but if the only things that existed were things I had done then this world would be a lot smaller than it is and many things people take foregranted would not exist. But assuming I did do all of those things where would we be? Still no where as there are 6 billion people to go proving things to.
No, none of what I present is Absolute Proof but surely we should not fail to investigate something simply because it MAY turn out to be wrong.
