Because common sense.

Good read.

I don't believe in a God or God's as there is no evidence to suggest that they exist. If there is convincing evidence to suggest that the universe was created by a deity then I wouldn't be an atheist anymore.

No.  He should not have.  He should have said what he meant, and as far as I could tell he didn't mean "it makes sense to me".  He meant "it's common sense".  The topic was about why he's an atheist, and that was his reason, and that was the best way to express it.  He should not have to tiptoe around the issue because someone might be sensitive, especially in a topic that was seeking out atheist opinions. If his honest opinion offends some people, so be it.  He didn't attack any person, he commented on an idea.

When ideas are not based in common sense, we call them out. If someone advocated an obviously flawed political policy or fiscal policy or view on physics or science or if they said the Wii U will be the best selling console this generation, then we would say that person is not showing common sense.  It doesn't mean necessarily that people who believe it are stupid, but they are wrong on that particular topic.  I feel (if that makes you happier) that a theistic world view is not based on common sense, and I do not think that there is anything wrong with commenting on that opinion as we would an opinion on any other topic.

Well, that all depends on what the belief is and how strongly you believe it.  There is a difference between having a hypothesis (which is what string theory is so far as I know) and to believe as absolute fact, and live your life by the rules of something that is not based in the data.

I believe it was Carl Sagan who was asked if aliens exist.  He said something along the lines of, "in my gut, I feel they do, but I try not to think with my gut".  It's ok for example to think that maybe there is an afterlife.  That is somewhat rational.  But, to live your whole life on the assumption you will get a second one, and to follow arbitray rules in order to attain it would be irrational.  

God has not given not one predictable outcome, as science has given millions. God proving himself = 0. Science = to high to count.

Understood. I don't take offense.

I think out of hundreds of people I know who believe in the afterlife (or a god) in some form, only a dozen or so are that fanatical about it. And even they don't follow the bible strictly (I'm almost certain they've continually involve themselves in pre-marital sex, for example.) Internet and college athiests really do exaggerate the religiosity of modern Christians, in my opinion. At most I think everyone can recall the whacko fundamentalist family member or two, but most people are quite reasonable about how their religion affects their lives, and many people don't even really practice an "organized religion" but still believe in the afterlife and god in some fuzzy general way. 

As for string theory, the amount of dedication and love for the hypothesis is quite "religous" I'd say. But it isn't so unique in the field of physics. We have had a history of epicycles:  luminiferous aether (late 1800's), Kaluza-Klein theory (early 1900's), etc, etc where very scientifically-minded people just couldn't give up their hypotheses because of their emotional attachments.  It really tells a lot about human nature that the most empirical of the sciences also has a large amount of intuition and emotional reasoning in its academia, and in many cases fervently so. In some cases this is a bad thing which impedes the progress of science, in others, particularly when they are on the right path, it can help science flourish through sheer motivation. 

I didn't realize there were so many atheists on this site until this thread.

I just see no reason to believe any sort of higher power exists that isn't just from a book or what have you. I need some sort of actual evidence to believe in god(s), and I've seen none. That's why I'm an atheist.
