I just a quick search because I know for a fact hell does exist, and found that hell is often confused with the lake of fire according to this website
http://www.matthewmcgee.org/helwords.html. Hell is referring to sheol (hades in greek) which is a place were souls go once they die the first death, referred to in Revelation 2:11. The second death is eternal, not the first death, and this is where the lake of fire exists as a place of eternal punishment and separation from God. This is where the confusion lies because hell is often mistranslated as to be the lake of fire but how can that be if on the final day death and hell are cast into the lake of fire according to revelation 20:14. So while you may have identified the confusion, to say that a place of eternal separation of God and punishment doesn't exist is blasphemy. Your right there is no connection between Satan and hell but there is between Satan and the Lake of fire. God warns of the second death, where there is the lake of fire.
Also points 2, 3, 12, 13, 14, 15 you made is your opinion. Hell is a real place, and the lake of fire is a real place, but they are not the same.
