It is possible to conceive of a single ruler of a realm but impossible to conceive of a singe reactor of everything.
"Conceive" in the truthful sense.
It is true that a ruler of a realm might grow so immensely powerful that he can make claims to creating the cosmos by sheer intimidation. It is not possible to convince a philosopher that there is such a thing as a Mono-God.
The world was created by itself, by roots that grow where no one knows, except me.
