O pshaw!

"stating that he and I cannot show that evolution happens."

Don't be so thick Troubie! Snail stating nothing of the kind.

Here is a teaser for you. How can you both claim that evolution is "true" and claim that you are being an open minded adherent to scientific principals? You say that the Turkish building caused the following. The scientists have accepted that they were wrong and accommodated the new knowledge into an enhanced explanation of social evolution.

Is it totally impossible that new evidence may be found that affects the theory of the evolution of life in the same way.

"True" is an absolute and a binary state. Things are either true or they are not. Good science is not. Science has lots of gray areas.
