Protector of Mankind

If religion is the protector of mankind and the ladder of progress, then why is there so much progress for non-religious people and nations? Religious people and nations or why so much decline? There is no doubt that in the so-called religion we are the greatest, the greatest there is no inferiority or deceit in the ego? Because what is the harm of religion, who has done it, why has it been done… he is always careful about these things but does not pay any attention to the plight of the mind. I don't think there are any qualities in a pagan or non-religious nation that have resulted in the birth of almost all great scientists, great philosophers but why aren't there any people to be mentioned among the pious nations? Is it because of such serious faults that most of the selfish, lying, arrogant, greedy, abusers of power, looters, demons are being created in the religious states? The nation will benefit if we think about these and try to change. Moreover, my religion is the greatest, the other is evil, repeatedly, from time to time such lies can not bring any benefit. Which is a proven fact.
