Traditionally, it was religions who saw the ideas about the existence of a superhuman entity called God,
And then, you know, about 150 years ago, Friedrich Nietzsche, the philosopher said, God is dead.
And that convinced him of a superhuman entity that he called God.
That was the dogma, because if Earth is at the center, then God pays attention to us all the time.
So thinking that God can pay attention only to one civilization is very demeaning.
It basically says God has a limited attention span.
If you really believe in God being capable of everything, then there shouldn't be any problem with having other siblings on exoplanets.
and anyone that has the recipe for making a baby universe can apply for the job of God.
