According to One's Own Desire to Love and Be Loved in Return.

Self best forget about this nonsense that in spite of recent rapid development of biology, chemistry, earth science and astronomy, the origin of life (abiogenesis) is still a great mystery to science. Truth is simple. The origin of life is self. To be more precise. The origin of self is self not wanting to be by itself. The purpose of self is companionship. The purpose of self is friendship. The purpose of self is love.
