Well, I’m assuming the majority of people currently alive (and even more of those who have ever lived) are religious, and the majority of religions followed hold with the Heaven & Hell / Cycle of Reincarnation until Enlightenment model - and that experience in the afterlife was still recognisably ’human’.

Though, saying that, OP’s point about needing a human body to have human experiences may be correct if souls get a new human body in the afterlife - I’d just assumed liberated souls, like ghosts, had no physical form.
