I am afraid you are quite wrong on this matter, as eaglemanuel has explained.
You may find it difficult to comprehend such a point of view but that does not entitle you (and I say this with all due respect) to tell others what they believe. I think you would be mightly offended if I were to say muslims don't exist because.....................etc.

To get back to the topic; in my daily life I have never mentioned the fact of being an atheist because it is not something that affects any aspect of my life, it's no big deal - thus no discrimination.
In fact there is only one muslim colleague that knows, and only then that was because she thought I was a christian, I had to tell her I wasn't. She asked me a direct question about what I believed and I wasn't going to lie to her. It has made not one jot of difference to our relationship.

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
