So here I am, trawling the internet and I come across this thread and I've never facepalmed so hard in my life. Atheists believe that there is no God and as an extension, there's no Satan. If you find atheists that are promoting Satan then they're not Atheists, they're Satanists. Stick to your fairytales and we'll stick to trying to find the true answers of the origin of the universe etc.
