2 Peter 2:4 “For if God did not spare angels when they sinned, but sent them to hell, putting them in chains of darkness
to be held for judgment”
God allows some fallen angels to come to earth and some are chained up awaiting judgement. (We can know from the NT that demons were/are on the earth.) Remember, God is in control and angels can only do what He allows. It must be for our sake that He does not allow all evil forces to be in the earth.
Job 1:7 “
The LORD said to Satan, “Where have you come from?” Satan answered the LORD, "From roaming throughout the earth, going back and forth on it."
So clearly Satan was on the earth, and also when Satan tempts Jesus in the desert, he is clearly on earth.
Also, Revelation 20:10 says “
And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and ever.”
Seems to be a future event, describing the second future Hell, that perhaps the devil is not currently
being tormented day and night in the current Hell, but allowed to tempt the earth to the extent that God allows him. When Jesus comes, the
”prince of this world” will be overthrown once and for all. As Jesus says, in John 16:11, “…
the prince of this world now stands condemned” Hallelujah for that
