one example of sheol in the old testament is book of ezekiel 32:17-32 where it is said that many great civilizations of the past are now in the realm of the dead, which includes assyria, egypt/pharaoh etc, that is the sheol where the "uncircumcised" lie, aka the enemies of the jews.
nephilim was originally a word meaning "giants", its once again almost a metaphor, referring to the nations that were so much bigger than the nation of y'israel (the jewish race), the story of david and goliath is a story of the small jews triumphing over the bigger nations that attacked them like babylon and egpyt.
nephilim was eventually translated as "giant men", and thats why book of enoch is not considered canon, because it bypasses the analogy and goes straight into literal interpretation, and the book of enoch considers these nephilim (half watcher half humans) as the source of evil today, because their bodies were destroyed in the book but their spirits still remain and they posses humans today and make them do bad things, this lays the foundation for exorcism in ancient and modern religion, but its not considered canon regardless.
its worth noting that the entirety of the old testament is told from the perspective of the jews, meaning all of their enemies are thus in these stories conflated with evil or some metaphysical evil, and they are represented as the good, but really its just a racial supremacist book and the people born to jewish communities are brainwashed by these books and turned into racial supremacists themselves.
in the old testament prophecies about the ha-moshiach, the messiah will come and enslave all the non-jews, and bring about world to come (ha-olam ha-ba) which is the paradise on earth, and the only people allowed will be jews, righteous gentiles and the rest of the peoples souls will be destroyed, that is rather "thrown in the sheol where they will cease to exist" just like in ezekiel.
meaning for most theres no afterlife, only nothingness.
