The bible never ever describes death as "cessation of existence",
Ezek 28:
15 “You were
blameless in your ways
From the day you were created
Until unrighteousness was found in you.
16 “By the abundance of your trade
You were internally filled with violence,
And you sinned;
Therefore I have cast you as profane
From the mountain of God.
And I have destroyed you,
O covering cherub,
From the midst of the stones of fire.
17 “Your heart was lifted up because of your beauty;
You corrupted your wisdom by reason of your splendor.
I cast you to the ground;
I put you before kings,
That they may see you.
18 “By the multitude of your iniquities,
In the unrighteousness of your trade
You profaned your sanctuaries.
Therefore
I have brought fire from the midst of you;
It has consumed you,
And I have
turned you to ashes on the earth
In the eyes of all who see you.
19 “All who know you among the peoples
Are appalled at you;
You have become terrified
And you will
cease to be forever.”’”

Malachi 4:
“For behold, the day is coming,
burning like a furnace; and all the arrogant and
every evildoer will be chaff; and the day that is coming will set them ablaze,” says the Lord of hosts, “so that it will
leave them neither root nor branch.” 2 “But for you who fear My name, the sun of righteousness will rise with healing in its wings; and you will go forth and skip about like calves from the stall. 3 You wil
l tread down the wicked, for they will be ashes under the soles of your feet on the day which I am preparing,” says the Lord of hosts.
if your view was correct, then mankind doesn't actually exist
I find your logic illusive just then
and this life is an illusion.
But we know that we do exist, so your view is based on false doctrine.
According to God everyone s already dead, so what is death. If we are born dead in sin, then death is not the (cessation of existence) death you believe in. To the contrary, the bible confirms that sinners are born (spiritually dead) and then they die a second (spiritual death) which is their eternal state. They remain in their spiritually dead state for all eternity, but they are fully conscious and they feel pain just as much as thy do now.
So, we need to find out what the Biblical description of death is, before we can draw to any conclusion on the matter. From what I see, your view is not supported by any scripture. Satan is a Spiritual being, He is not made of flesh and bone so the description of His burning up to ashes on the earth must be referring to His power as the Prince of this world. He is stripped of all His power and He will never be reinstated as the Prince of this world.
The Bible is clear that on that day (when we step into eternity), everyone will be resurrected and reunited their own bodies. Those who died in their sin will remain in that state forever, but those who were saved will receive a glorified body and we will be perfect and sinless like Christ Himself.
"cease to be forever"
"wages of sin is death but the gift of God is eternal life"
destroyed as in "by reducing them to ashes" 2 Peter 2
No doubt the second death of Rev 20 does involve a great deal of suffering and torment but it ends just as Ezek 28 states even for the devil himself
