There is no step 5.
I heard on a Bible study program this morning the teacher say "There is no 5th Kingdom"

start listening at about 30 minutes in. Or listen to the whole thing.
Daniel Chapter 32 thru 43:
Daniel interprets the dream of Nebuchadnezzer, (The first “Chad”)
These are the earthly kingdoms that will rule before Christ rules on earth. There are 4, there is not a 5th one. The next one will be Christ ruling on earth.
Its going to be Biblical.
Bonus verses:
Notice verses 41-43 describing “diversity is my strength” bullshit.
