If everyone were humanist, would the world be a better place?

I think if everyone were humanist, the world would be a much better place. If we stopped believing in religion, esteeming a certain group of people and not caring about other living beings, and lived with the mentality of reducing suffering and increasing happiness for everyone, we would be a more developed and sweeter planet. What do u think about that?
