Each religion has main two components.
One is preaching way of life, and second is description of god , his power his charm and his relationship with man.
As far as first component is concern, the rules and regulations preached before 2500years, in the desert of Arabastan is completely out of date. Because the life as changed a lot. The rules prescribed for tribal ace not any way useful and beneficial to the present modern and scientific community.
Even to-day there exist some group of people [very closed minded] who vehemently insists that those tribal rules must be implemented to-day. This is very sick mentality. Those who cannot co-op with the progress of life, try to put hurdles in the progress.
The second factor, is God, and his relations with mankind. The existence of god is very much doubtful. Those who claim that they have seen the god, or god has send the messages through them, are either dreaming or hallucinating. In hallucination person can hear voices and can see the images, which has no existence.
So the subject of God is purely abstract. It is the idea created by some intelligent group of people, to frighten the mankind, and to have smooth running of society.
Now to fight and to try to prove abstract being, as real is absolutely unscientific. To try to prove that some religious book, written before 2500 yrs, and written for different culture, is purely scientific, is absolutely irrational and unscientific.
One fellow was traveling through desert. He was very tired, hungry, and thirsty. Then at far distance he saw abundant water and lot of greeneries. It was mirage. He was pleased. He thought that it will be helpful for other traveler to find out such water spot. So he draw the map, Which was passed on to generation to generation.
Some other time some other traveler also saw abundant water with greenery. Again other mirage. He also prepared the map, so people can reach to that so called water spot.
That map was also passed to generations.
After few centuries, some young person found one map, and some other young person found second map. Both were travelers. They tried to compare both the maps.
Directions shown in both the maps were completely opposite to each other.
So then they started arguing one fellow say my map is correct and your map is wrong, other fellow says that no my map is only correct map. From arguments they started fighting. Then there were two groups, one group was in favor of first map and second group is in favor of second map. Both the group was saying that their map is most scientific and authentic.
With the passage of time some new maps for that so called water spot was prepared, by some other travelers. Everybody claims that their map is most authentic and scientific.
Fight is still going on, because nobody has seen water in desert. Everybody was fighting for their delusion.
