God
Gods were beings of divine power from the mythology of many species. The powers, abilities and appearances of the gods can vary greatly from culture to culture. Some might consider Transcendental Beings to be true gods, due to their immense power.
The Doctor didn't believe in any specific god, but had met a number of beings claiming to be gods. (DW: The Satan Pit) However, when the Doctor once stated when someone asked what Christmas is he said 'I should know, I was there. I got the last room'. That means he may have been in Bethlehem at the birth of Christ, as he implies he took the last room at the inn where the stable was where Jesus was born.
