According to Sacre Scriptures, Gospel, Catechesis, Catechism and so on, could Jesus have had, or could have, one or more brothers or sisters?

I'm not referring to terrestrial brothers or sisters who lived during the time Jesus has lived on the earth, which, however, would be in disagreement with the dogma of the Virgin Mary(1), but to brothers or sisters that lived on other planets where other kinds of extraterrestrial beings live or lived.

Or, in case, did God send always Jesus, the same son who went on the earth, on these planets?

I'm not looking for an opinion based answer, but for an answer that describes the position of diffrent christian churchs on this matter(2).

(1) However, there would be the problem to exclude the circumstance that Joseph, the 'father' of Jesus, did not have other son/s with other women.

(2) If it is unclear, the matter is what the position of christian churches is about extraterrestrial civilizations and their need to be saved.
