I think it really would depend on what you mean by " god" as thats different on so many levels for a different culture...
Taking it on the judaio-christian family ( christian/catholic/Judaism/islam/etc ) it's one thing, as " and lets not get offended were going off historic time frames" are one of the younger of the " mainstreams" that have also splintered heavily in that time would cause reactions to be very very differnt...the fall out of basically wiping out the christain view will be different than how lets say the catholics may react ( and there would be alot of finger pointing with all of them as to who " set it up"
Take it to a Buddhist....we'll just smile and say " I know" as "Buddha" is not a god.. in fact " buddha" is not a single individual, it is a rank, or a title.. though " Buddha" as most often referred to is the FIRST one, prince Siddhartha Gautama.. who in his own words is " just a person"
though some culture has added alittle local cultural flair, the western idea of " who/what " is a god is so radically different..and as the 14th Dali lama has made clear ( though he is of a different lineage than I, " When Science can prove something that goes with Buddhist philosophy, then it is a great comfort, when it finds something that contradicts the teachings, then it is for the better ( meaning science wins out )
Just so I don't ramble on, I'll cut it short, Had I the ability to show the world? I would consider it, but at the same time, despite the hate and violence many ( pretty much all) faiths have on their hands.. they also have their good sides, and offer something, even if with or without slight misdirection to those who have nothing..
if someone who was christain, taoist, islamic, pagen, shinto, or any of the others came to me and ASKED to see what I found regardless of what it suggests to them of their faith, then I would, and with a warning of how it could change them deeply, I would never FORCE it on anyone ( and as said before, there will be many who will chose not to see it at all as they blinded themselves to all possibility but the ones they deemed to be truth"
which is why I also say...
" truth" is color as fact is stone.
