What does Mother is God to the eyes of a child mean?

Ah, this is also from (2006) Silent Hill.

Well, if you're a christian, or have 'heard' of God and such.
That 'God is powerful, can do anything, made you' it's a strong reference to our mothers. Our mother's ARE powerful, they teach us, feed us, help us in life, and their love is powerful.

Basically, Mother, is a child's god.
