To me 'Son of God' is a honorific title of jesus bcos he is sublime. "Messiah' is a traditional title for the jewish kings. Yahweh is the omnipotent God beyond our understanding nor I think Yahweh needs human helpers. The Holy Ghost is the human conscience. However if one follows the fundamentalist story telling, one can't help pondering on the followings:

OK, God behaves like a person and has the attributes of a person, like he could get angry and wants to be worshipped. He did not originate from Planet Earth, he has supreme power and he is beyond time and space. So technically he is an advanced ALIEN in the sci-fi sense. And then there's the 3 in 1 trinity. What is the identity of the Holy Ghost which is God or at least a manifestation of God? How did he come into being? Could it be that the Holy Ghost is a clone of the leader of a highly advanced alien species mainly consists of what we know as 'angels'? Angels can fly and arent we always associate ET aliens as creatures that flew to earth? Are angelic wings just levitation suits those aliens wear? The biology of Yahweh the alien honcho wasnt compatible with the homo-sapien genes but however Holy Ghost the clone could engineered to be compatible. So Virgin Mary was abducted, impregnated by the Holy Ghost and gave birth to Jesus the alien-human hybrid which can be considered a form of cloning but with additional human genes. So we have the 3 in 1 trinity, just a way Yahweh exercises his rule on planet Earth. For a planet inhabited by intelligent reptiloids, Yahweh will exercise a different type of multiple godhood and the jesus equivalent there could be a chameleon
