Intelligent design implies there is a specific, finite beginning to at least one event in the history of existence. That doesn't mesh with anything that we know about physics.
Natural-selection evolution is by definition the way pretty much everything in biology works, but it's more "survival of the adapted" than "fittest." "Fittest" can mean the same thing but just has connotations of strength that don't need to be there.
The truth is that atheists bend science to try to justify atheism.
the only time this ever really happens is when some atheist says "god doesn't exist and i know it for a fact because nobody's shown me the existence of god like science says you have to" and that's because science doesn't allow you to prove the non-existence of something
those people are generally teenagers and that take is generally made within high school cafeterias
