Of course not
Atheists believe in facts, so what we do believe in has already been proven. Religious people can't say " well you can't disprove my God, therefore he exists." A famous atheist once said " I can't go up to people and say ' Prove that I can't fly', they'd go ' what do you mean prove you can't fly? Prove that you can!'" That is exactly the same thing. We've already proven what we believe in, now it's time for you to try and prove what you believe in... Without using the word faith.
