To know the science behind this inquisitive nature of human being we need to know about the human being as a life atom and not this physical body.
The whole point becomes clear when we understand the existence itself off the human being.
He is a soul a life atom inside a physical body trying to know and understand himself. That very objective is the soul purpose of this fusion.The frontal cortex in the human body is developed enough to give and receive signals from the life atom.The whole bodily journey is to understand the universe and itself.Language is the medium and asking questions is the action item.
Society has not been able to promote it and eternal bliss for all humn beings will be possible when we have a culture of asking questions without fear in the society.
