Why are atheist...atheist?

[Cinjin]

Also, I've asked the question elsewhere but didn't get any informative answers at all. They very much responded ignorantly as if they were offended or just assumed I was speaking from the common religious point of view when i wasn't. Since yahoo answers isn't really good place for you to say "no, you completely misunderstood what I've said" or " you didn't even read what I wrote" I decided to ask the question on forum instead. In fact, the only plausible answer I got from one person was that he chooses the stance of atheist because he chooses not to call anything he doesn't understand God, which is really admitting you simply do not know; which is what I've suggested was the wiser path. However, I know that not all atheist are like this though, which is why is re-ask the question here.

Look man, atheists don't appreciate people like you telling them what and why they hold the position they do. I'm going to show you in RED how many things you should be prepared to explain, defend, or deny when the bulk of this forum shows up to read this. Being inquisitive is fine, but you are INDEED making ignorant and slightly offensive claims here that you're going to have to own up to. You've even already admitted this by letting us know that another forum was angry over your choice of semantics. You honestly need to learn how to ask a question without providing your own insulting answer to that question.

Far as i know, atheist choose to believe that God does not exist. My question is why? I, myself, am spiritual and am not really affiliated with any religion. I choose to believe God exist because I think the laws of physics just randomly or coincidently happenening the way they did out of the infinite other possible options is rediculously unlikely. So unlikely that i choose to believe in some intelligent design instead. As far as what God is like don't know. Is he an individual, a collective, or more like a computer with no real consciousness as we might call it? I couldn't answer with as much conviction as believing in God, but I do have my beliefs about his nature.

But to just assert that God doesn't exist without any real supporting evidence is just as ignorant as religious people saying he does exist and describing what he's like. To me, it sounds like Atheist choose not to believe in God simply because it makes them feel more sure of reality, same reason religious people choose to believe.

Why not simply admit one does not know instead taking a stance of certainty? That, to me, is inherently ignorant.

By the way. I'm not an atheist. I just know better.
