Man’s earliest prereligious fear of the natural forces gradually became religious in nature and got personalized and spiritualized. Eventually he learnt to say 'God works in a mysterious way'.

In the beginning of our love lives, it is the beastly instinct of sexual attraction that drives us all. The butterflies in your stomach simply signal your mind that the person in front of you would make a fantastic mate to make babies with. Without this primeval drive, you won’t ever fall for anyone in your entire lifetime. The very attraction you feel towards a person in a romantic way, is a mental manifestation of a subconscious desire to mate with that person.

Good and evil are both within us. And when our primitive ancestors humanized these natural qualities of the mind, they got two completely opposite supernatural characters. One was the merciful lord almighty and the other was the wicked devil.
