Reincarnated in the Middle Ages, I Am the Father of the Galaxy

Anyone who built a starship in the Middle Ages knows this. Just need to add a little motivation, add a little motivation, add a little motivation... And add a little Star God technology. You can click on the copy of Space Age. —————— Sipress, who inexplicably traveled through time, found himself a priest on a starship. Even if he becomes a priest, why is there a sleeping Star God in his mind? Even if there is a Star God, why does this Star God have the same name as the Mother Goddess of Humanity, the highest, strongest and greatest Mother Goddess they say? Okay, okay, okay, I really can't do anything about you, just the same name and the same surname, so what does it mean to become stronger by collecting human beliefs, and what does it mean that there are exactly hundreds of billions of "people" here? Gradually, Sipress realized. The father of the priest is the father of the father of gods! … But first, what he has to do is survive in this world full of madness and religion.
