There are many myths surrounding LORD. One of very basic is that he already have a Son.
Also LORD was thinking so for long time. However he has discovered on his father example that this star on the right ear is disappearing after the male offspring.
That way you can be sure that he do not have any. Only active LORD have it. Same star that is coming to the Earth every hundreds years.
It is a magic but would she hit the planet depends only from this one that have that mark on his right ear.
