which threatens the very core idea that any "God" would be concerned with only one world out of trillions Threatened? Ideas can't be threatened.
Where did you get this core idea, anyway. Having a concern, especially a specific one, implies vulnerability... if the concern involves some sort of distress related to potential outcomes. Like "oh no, what if these idiot humans screw up the planet?" The common idea of (capital G) God, Is one of omnipotence (omnipresence, omniscience, and omni-benevolence), can't be threatened by definition, that would defy the omnipotent characteristic. If having concern means only to relate to the business of creation then I don’t understand what the issue is. The idea of coming from one source certainly doesn’t violate faith, it faithfully points to a source, no less than a great bang of force from nothing does. If you want to argue a single moment and burst of creation from one source which then led to diversity of form vs the more playful view of letting this happen then letting that happen (Let there be light is my fave) culminating with a dominant creature, then fine argue away but one is no less based on faith than the other.
We know that none of us, or all of us, are great enough to have a completeness of understanding, even over the smallest of things; yet we can imagine a completeness… we do when we consider ‘The Universe,’ as if there is such a thing bounded in temporal existence. So pick a set of delusions and argue away, seems to me it all ends up right where it started, in an eternal moment of determined possibilities.
