When does life begin?

From a commenter on my most recent post, γεννηθὲν:

"The ESV renders Ecclesiastes 11:5, 'As you do not know the way the spirit comes to the bones in the womb of a woman with child, so you do not know the work of God who makes everything.'

"As said above, we should think twice about claiming to know with precision what God says we do not know!"

This has direct bearing on this earlier post as well:  Contraception and Murder.
