Space is vast and so too are other areas of space - or as you call - planets
or stars where the idea of a deity or deities exist.
The more common is the idea of brothers - sometimes several deities and in
some cases a woman.
The idea of a deity visiting the planet or area of space or star in their
charge and performing wonders - is also quite common, but not as common as
you would think.
The one god is not very common - the idea of a one deity being a kind of
freak with no real friend to turn to - does not appeal to any with
compassion or understanding and brothers or groups of deities far more
common.
Inhabitants like to think their deity or deities best and more powerful than
any other - but once space travel and communication occurs - it really
becomes a question of my Dad is bigger then...

The idea of angels is also quite unusual. Deities are generally considered
powerful enough to operate without assistance.
