Are atheists really atheists as they claim?

I’m pretty sure that most knowledgeable people know that someone who claims to be an atheist is just making an overstatement about his/her own beliefs. As most knowledgeable people who claim to be atheist probably know that even the most recognizable  faces  of atheistic propaganda, such as Richard Dawkins, admitted publicly that they are less than 100% certain that God/gods don’t exist.

My question is: Why would anyone who calls himself an atheist make a statement like that?

How Did The Designer/God do it?

I’m pretty sure that many creationists/ID proponents and skeptics about materialism have heard that question many times often when materialists get  cornered about their beliefs about the origins of life…The usual question posed by materialists is: How Did The Designer/God do it? We can’t recreate life, so tell us how was it created!

Does anyone have a theory about how ID/God/ET did it?

I have my own,  but I’m just curious how much smarter people than me would answer  the skeptics who often add to their skepticism: Did ID/God/ET just “poofed”  life magically into existence?
