... I guess that would make corporations demi-gods?
"Heracles Inc. is now in business! Excuse us while we beat our subordinate companies to death in a fit of unthinking rage. Twelve decades of fines, coming right up!"
Seriously though, it's not so much specific governments as collective action in general. Most of the things attributed to gods are things we as a species are either capable of, will be in relatively short order, or are actively doing. Floods, plagues? Victory in war, great constructions? Near every miracle -- and definitely every miracle worth note -- is something mankind has already done, and what few aren't are within our technical capability either now or in the near future. And barring disaster, our capability to do so (technology, methodology, etc.) will remain indefinitely. Power, immortality (or at least immune to aging), right there.
It'd just be really expensive and kinda' pointless to turn someone in to a pillar of salt or somethin'. We could do it, via tiny machines or whatev',* there's just no reason to, 'cause it's stupid and cruel and wasteful and etc. The good stuff like small-scale geo-engineering, restoring sight to the blind, limbs to crippled, the dead to life, we already do (to varying degrees of effectiveness. Getting better on all fronts, though!).
*We might even be able to do it pretty quickly if you consider "turn in to" to be "spatially replace and render the former matter nonexistent". Just have to figure out how to shoot a lot of salt at someone really fast, which we could probably manage.
