If we define nothing as external to spatio-temporal properties as well, it doesn't exist physically by any coherent theory and it has no effect on anything.
There are vacuum states, but those are measures of the energy of the background fields (of which space time is one).
If we define "nothing" as a space time field with no matter fields within it, nothing is just a simple Minkowski metric. There we have it: God is a linear matrix. Not really something to be devoting babies to and having prayer rallies for in my opinion...

"Listen, strange women lying in ponds distributing swords is no basis for a system of government! Supreme executive power derives from a mandate by the masses, not some farcical aquatic ceremony!"
