i don't personally hold to exoteric religious thinking & an 'external' God - it's as mistaken as Atheism imo. Both 2 sides of the same coin.

Given how very little we know from a rationalistic/scientific perspective, to assume from that all that exists is a physical reality - is to my mind totally ridiculous - But humanity is in a lot of ways. Is that the fault of 'God'?

There are myriad reasons for why things may be the way they are on this Earth. There is certainly a vast amount of stuff that we could sort out as a species, if we became more genuinely civilised, but that very largely comes down to individual & collective responsibility & choice.
