Religion is the remembrance displays at an accident. The cut piece of hair that is kept. The deep longing for a person that has died. It is the way that people comfort themselves over the loss with the belief that life goes on after death.
It also becomes the tool others use to make money with, control others to gain an advantage and to make themselves rulers.
It is also the curiosity of what and why combined with our desire to find an answer. Maybe in the not too distant future, the whole concept will change of what people need in their lives.
I can only hope that religion as it is, as well as animosity towards other nations/races changes.
Although Pacific Rim 1 & 2 is just a scifi movie, it has continued to try to show a world united against an alien race. Still have people's annoying quirks and money issues but I enjoyed the feel of the movie with international casts.
