It's also very possible that when the Christian Bible was finally canonized all references to the Christ being a space alien would have been expunged.
There is a difference between probability and possibility.
It is possible that the Christ was married.
It is highly improbable that the Christ was an alien.
To equate His being married to being an alien is absurd.
Your use of "possible" referred to the likelihood that a given fact would have been expunged, not on the reasonableness of that fact. One surmise premised on disproving a negative is as good as another.
