To claim to "have seen it all" is much more astonishing as theory. Take conventional science, I think archeology has far more rational approach. I would say "A proven concept of exploring the unknown". Bla bla impossible! etc isn't going to do your study any good it holds no evidence.
archeology: The systematic study of past human life and culture by the recovery and examination of remaining material evidence.
I see a world of science full of remaining material, a system to study it doesn't exist. In stead I see lots of ignorant "we know it all".
I have more as enough evidence to back this up.
