Different?

We know how the result of a War would be after several times of experiences. Misunderstanding of emotion could be an enough reason to kill each other? Must we do that childishly? We are so stupid enough to do that? Is it a so big wall as not to be overcome, the difference between religion and ideology? What is written in the Scriptures are all correct and the truth Scientifically? We must have lost a good reason to fight except in sport athletic field now after the proof of the similarity of Genome Identity at the rate of 99%!
Additionally, no border lines are recognized from a satellite like that on Google Map.
We have no reason to fight nor to kill each other, because we are exactly the same if the color of the skin and of the eyes were different each other. So, let me know who on earth denies my fundamental opinion?
