Take a moment on a dark clear night to go out and look at the sky, if the sky is clear you might be able to see two or three thousand stars in sky, You can see the zodiacal lights. If you really pay attention you can see a smudge here and there, the most prominent of which is the Andromeda galaxy. Realize now that the universe contains around 2 Trillion of these within our visual horizon and even more beyond that, perhaps an infinity.

Each of those two trillion galaxies contains on average about 200 billion stars. That's around 4 x 10^22 stars, about 1-in-8 of those will have a planet in the Goldilocks zone, the habitable zone where liquid water can exist. Of these only a portion will be stable enough, have the right chemistry, not be tidally locked, be around a star that isn't so angry that it strips the atmosphere, to develop complex life, maybe 1-in-1000, but even if 1-in-a-million that is still 4x10^16 planets hosting complex life, and a non-trivial percentage of those will develop intelligence because the survival value of intelligence incentivizes it's development in evolutionary terms.

So our God likely presides over somewhere around 10^22 intelligent species in the portion of the universe we can see and likely much more beyond that, perhaps even an infinity.

Do you really think such a God could be owned by one tribe on one planet? Do you think such a God would encourage one tribe of his creations to slaughter another? I don't.
