1. People would have their own opinions, but respect those that were opposite. (People would listen and attempt to understand rather than refuse to see the other side).
2. People would be conscious of their effects on their surroundings (Earth, Animals, other people) and put forth an effort to leave things better than they found it.
3.Everyone would find pure happiness. (Happiness not made by money, power, etc but the same happiness I get when I'm galloping my horse).
As far as your question, Sunny. I think most people are not atheist. They are more agnostic. Humans are full of fear, and fear of the unknown is a good thing. Everyone wants to believe that their life has meaning and that this is just not chaos. I just think some people either don't know what that is (it's hard to be 100%) or they are scared off of religion because of the debate and politics.
