Let us see the inner and hidden meaning in the Adam and Eve concept :
So God created the human species for the soul development to the higher stages.
And entered the souls of two animals into the bodies of Adam and Eve, with the primary importance to the "intellect" in man and the primary importance to "experience the feeling" in woman. This way the core nature of the Dualism in this physical world had taken place. As the animal species cannot express the divinity, human has given the Thousand petal lotus flower "Sahasrara Chakra".
