Religion is a disease. It's probably killed more people than the bubonic plague. And it continues to kill today and it will continue to until it destroys everyone. Religion is clearly man made and anything that a man makes has a reason. Religion was made in ancient times when people were ignorant in order to make some sense out of life. To provide a meaning. Whoever came up with these religions of course were in top of the food chain - call it a side effect. In different parts of the world different religions arose out of the need to understand life and to find a deeper meaning. When populations exploded, suddenly different religions had their first meetings, and the position of powers that creators/their offsprings of one religion held became challanged by the creators/their offsprings of another religion. Who is better? Like in the animal world someone has to be stronger. Man is an animal. Someone has to be stronger and bigger. Hence began the fight for supremacy. Which religion is better and more powerful and greater? Religious leaders from each religion were not going to let some other religion undermine their position of power. Hence there is war to justify religion, which originally stands for the creation of man itself. I could go on but in this day and age, we need to understand that the only religion we need is HUMANITY. No religions, but if you need to follow something then follow the religion of humanity. Only then there is any hope of a better world.
