If that were liberating, it's hard to see why religious fantasies would have persisted everywhere for so long to blot out nature's godlessness and inherent absurdity. Sure, we'd be free of religious tyrannies, but we'd have to face the unfairness of life and the finality of physical death.
It's not so easy to suspend your disbelief in the context of postmodern hyperskepticism, so the question is whether we could be content with our subjective truths and fictions, knowing that the real world is inhuman and indifferent to our preferences.
Perhaps the only salvation here would be from transhumanism, from an all-encompassing transformation of nature to make us more godlike and less vulnerable or fearful.
