I'm sure different denominations and different people will have different interpretations, but a popular one is that it's actually supposed to say "only begotten son", whereas Adam and the rest of humanity are children in a lesser sense (in lack of better words). If one creates a robot, one can probably feel an emotion of love towards that robot, but one is more likely to feel stronger love for an actual child.
