Please elaborate on why you think an Atheist has faith.

An atheist exercises faith i.e trust or reliance upon something that cannot be proven when they trust in their cognitive faculties. They also trust in the scientific method even though the scientific method itself cannot be deemed reliable by alluding to what it has shown to be true because to do so would be to argue in a circle.

Scientist and atheist alike believe, trust in, have faith in the findings of science and that their cognitive faculties present them with a true picture of the world they live and work in even though neither can be proven without arguing in a circle.

You seem to be confusing atheists replacing faith with science, you are wrong. I have always been an atheist even before I knew anything about science.

And of course atheism was around before science.

There have always been people who found religion unconvincing.
