What I find interesting is that so many of us on this thread disagree about what color the sky is, yet we all agree on this thread.
You would think he would notice that and think that maybe he is wrong, after all.
Number of believers in a concept or topic is irrelevant to the actual truth of the concept or topic. There are millions of people who believe that a god exists yet they are all wrong. Just because a lot of people are delusional it doesn't mean they are right because there is a lot of them.
People are very sheepish and go with the flock. They never challenge anything put in front of them, or else they wouldn't even be religious in the first place let alone think they are right because their neighbor agrees with them.
