... they didn't deserve to live before the age of 30 either.
'Only 30!' the majority might cry. 'So young'. Not in the slightest. The Beatles had done their work by 30.
If you are even half way likely to become a notable person in the arts (including music), medicine, architecture, philosophy, sport, generally being caring and creative etc you will have made in-roads if not formally then at least in your own self education.
Most people are not skilled even particularly moderately in these kinds of things. They haven't developed the intellectual / emotional apparatus to be capable of things like true compassion, team playing, assessing the most moral thing to think or do. Instead they see the world through the prism of their own deficiencies. They might occasionally admire someone of great skill but only in the way that someone would be physically 'impressed' by someone bludgeoning them over the head with a mallet- it's less a case of finely tuned respect for talent and more a case of a neurological reflex to 'applauded difference' i.e. if the talented person in question was not being applauded by the majority they probably would not feel so strongly, if at all, about that person. Ironically, the people most guilty of it are probably those who claim to despise the celebrity culture. So programmed are they to hate any form of 'flashiness' no matter whether it serves a laudable artistic purpose that they only reluctantly relent to enjoy what resembles some (to them) more 'worthwhile' physical skill. When they applaud a great piano player they might as well be applauding a great plumber- the 2 skills are equivalent in their unartistic minds.
Life should be nothing if it is not art. All the other stuff is just the nuts and bolts to support the life that should be craving art. Whether you get your art from private introspection or travelling, you should never be flabby and/or passive. And so many people aged over 30 are that all they are doing is stubbornly existing, parasitically.
Just because people happen to frequently live until the age of 70+ doesn't mean that they deserve to. Nature probably doesn't work that way- if it did do you honestly think that very young children deserve to die horribly as 'nature' also allows?
Indeed, many of the greatest people - including musicians - who have ever lived died at an age younger than 30. Certainly by 40 they would have been fed up with how the external world works in comparison to how their own elaborate internal world works.
I hope that you can see how my post tends to emphatically deny that life is particularly Godly / good. People are allowed to be thick as two short planks, as harmful to the young as they like and more or less get away with it unless caught.
And if the people who are allowed to thrive / live long in life (nor their supporters) aren't necessarily particularly Godly / good what reason to think that an afterlife would be? It would be liking putting up with an intolerable test and then, at the end, getting a pass based on not giving in to intoleration. Regardless of how talented you have been in life in any particular artistic skill. For if there was a God what point would there be to creation except for it all to be a kind of art project? What an ugly, dull, uncaring project to some of its star players.
God is an understandable explanation for how any stuff- especially consciousness occurred- perhaps even the best one (although that doesn't mean it happens to be the correct one). But God as we defgine God is not in the slightest an understandable explanation for why consciousness is- and has been for many many centuries- so messed up in so many people. I have seen good people, people who would not hurt a fly, people capable of quiet warmth and humour, completely ignored for years on end by most people. There is no consistency in this- none at all - with there being a God as God is defined. The good not only die young, they die entirely ignored, they die pitied, they die in flames, they die urinated on and sexually abused. And sometimes so do the good old. Please rethink whether this is consistent with there being a God. Doesn't it seem to be far too much like an intolerably 'long game' for God to be likely?
