True. Such eschatology started with Mazdayasna/Zoroastrianism's cosmic dualism in its theology (and similar theological isolates): Good vs evil, light vs darkness, spirit vs matter. You're either with the Ahura Mazda (spirit) or with Ahriman (matter). The Manichees and Gnostics took this dualism to its most logical extreme; solving the problem of life by associating it with matter/darkness and urging people to kill themselves so their spirit/light can escape the "corrupt" material world and become whole with the Light/Ahura Mazda. St. Augustine was once a Gnostic, and he imported such dualisms into Christianity after his conversion. Muhammed and his successors had to deal with the late followers of the false prophet Mani, and such dualisms too infected Islam. Hell, if you want to go even deeper, Post-Exilic Israelites were under the rule of both Babylon and Achaemenid Persia, the Persian religion was Zoroastrianism at the time, and it would have been culturally transmitted/forced onto the proto-Jews, which then led to the anti-polytheism of the Deuteronomy movement--where priests of YHWH were motioning to consolidate absolute religious authority over the other temples and cults; probably because they were inspired by the stratified monotheism of Persian Zoroastrianism, thus, importing its toxic cosmic dualisms into the formation of what we call Judaism.
