People seem poorly informed on the subject of DNA. One most likely cannot create a person manifesting the kind of mastery of life that Jesus exemplified with genes from a Roman soldier. I am told that Jesus had 95% effective DNA (there's one molecule of DNA in each of the 100 trillion cells of the body), while most of us have about 35% effective DNA.
The other thing: It is known, from sources such as the Italian bible scholar Mauro Biglino and sources of galactic information such as Pleiadians (Jesus is the master of the Milky Way galaxy, not just Earth), that angels were not 'flighty beings with wings', rather human-looking entities with great power that walked around on Earth, that could emanate light energy from their hands, and appear and disappear at will (they were actually Pleiadians, who closely resemble humans, but live in the 7th dimension: highly advanced spiritual beings who can be both in the Pleiades and here at the same time).
Pleiadians were the ones who upgraded the human DNA in the first place to move us to the next level above the near-animal (took place a long time back, in the so-called 'Garden of Eden'). The angel Gabriel may have been the one with the DNA quality needed to create a being like Jesus, thus he would have impregnated Mary (in the usual way), leaving Joseph puzzled when she became pregnant. There's many levels to consider, for a being like Jesus to be born.
