>>>>>>"Man was polytheists before they believe in one God."<<<<<
You can replace "god" with "gods" in my post, it's still the same point. Atheism applies to both singular and plural forms of god. What was man before he was polytheist?
>>>>>>"Man has always believe in some form of divinity."<<<<<<<
I'm sure there have always been men, like myself, who did not believe, even during times when most men believed. I am living proof that not all men adopt a belief in god(s).
>>>>"From the beginning of man, we have had a need to believe in a higher power of some sort."<<<<<
How would you explain an atheist? I do not and have never had such a need. I have always been an atheist, even though I have considered all belief options and I have an open mind.
We can get into theories about when humans started believing in (supernatural forces, divinity, god, gods, animism) but I doubt humans have always had those beliefs. At some point the concept had to be thought up. Of course I believe humans evolved over millions of years, and you probably believe the earth is 6,000 years old (I apologize if my assumption is incorrect), so this changes our perspectives. By my definition of evolution there technically must have been atheists before they were even able to form the intellect neded to contemplate god(s). Your definition of evolution probably comes from the bible, so we are talking completely different reference points.
