What is to be taken literally?

quote:

I know that people can experience such severe brain trauma that they forget who they are. They have to relearn walking, talking, etc. After they have done this although their body is recognizable to their family they not only don't remember their family but they don't remember who they were and are a different personality, with different tastes, moods, styles of expression etc.

That seems to support an argument to a wholly material existance; thats exactly what one might expect to see if behaviour is a programme that had to be re-written.

And while we are on the topic of gods physicality, I want to ask about navels. If man was created in gods image, and man has a navel, does god also have a navel?And if so, who gave birth to god?
