A fairly leading theory why their able to learn languages is while most of the grey matter is present during that age many pathway connections inside the grey matter are formed which could allow them to make the connections necessary to learn the language. However as you age your ability to make the same mental pathways decreases...
Touché good sir. But that doesn't make a child able to process the same amount of information that an adults brain is able to. The connections may able to be made more easy as a child but the potential for the ability to actually utilise them to the maximum is limited, as throughout the Oral stage to the Genital stage of development (Roughly 0-16/18) the human body is a battleground of hormones that can override these singles at times. (This is going to become Biology vs Psychology isn't it... )
