I suspect the historic kernel of the 'divine birth' myth went something like:
'Sabit! I'm home from the wars!'
'Ibal! I've missed you so mu...'
'Wait, Sabit - I've been gone a year and you're with child! Harlot!'
'No, Ibal, it isn't like that. Erm...it was Enki. Yes, the great god Enki appeared and made me pregnant. That's it.'
'Oh, well that's all right then. What's for supper?'
