Evil spirits and undying entities though - not sure what really classifies something as a demon. God flooded the Earth to destroy these fallen angels that had ruined His creation…..but their spirit didn’t die. They were incarcerated in Tartarus, or the gloomy dungeons. But make no mistake, these were the fallen angels from Genesis 6 that cohabitated with human women and had children by them. Immediately after these passages in Genesis 6 the Bible goes straight to Noah and the flood.

If you want undeniable corroboration for this explanation check out 1 Peter 3:17-18. These scriptures refer to the exact moment that Jesus was crucified and what he did immediately upon resurrection.

“ 1 Peter 3:18–20 — The New International Version (NIV)

18 For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. 19 After being made alive, he went and made proclamation to the imprisoned spirits—20 to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built.

But in case you are a big fallen angel fan no worries - they are scheduled to come back (see Revelation 9:1-3). Just hope you are not around when they return.
