Death is not the end of existence.
It is when you die in a fire that God created.
How do you destroy a spirit anyway?
It's something easy for God since he is God and created everything. He certainly can uncreate anything.

If God is going to annihilate unbelievers, there is no reason for judgement.
No, God has decided that is the proper way to do it.
There is little incentive for people to repent.
For those who don't want to cease to exist and miss out on heaven there is plenty of reason to repent.
What is to fear if God is going to annihilate sinners?
You keep relying on imperfect human reasoning. Stop that. On judgement day, all the unsaved will be terrified.
Yet unbelievers will be terrified when Jesus returns. "Don't worry, the atheists are right, there is no existence after death". Sorry, that makes no sense. And it requires reading into scripture what it does not say.
That's completely false. Scripture is very clear that God is going to annihilate the wicked. Only eternal torture requires reading into scripture what it does not say.
Rev 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
A lot of negative things will not exist in the future.
Wiping tears away means no more tears. Tears will not exist.
There shall be no more death. Death will not exist.
There shall be no more sorrow. Sorrow will not exist.
There shall be no more crying. Crying will not exist.
There shall be no more pain. Pain will not exist.
"for the former things are passed away." That means they are gone, gone everywhere, gone forever. If those things existed anywhere then the scripture would be lying.
Tears, death, sorrow, crying and pain will be Annihilated and shall never again exist. Is it such a stretch that the unsaved wicked people will also be Annihilated? Scripture over and over promises that they shall be Annihilated. Believe what scripture says and reject false doctrines that teach otherwise.
John_3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son
shall not see life ; but the wrath of God abideth on him.
"shall not see life" means will not be alive.
Mat_10:28 And fear not them which kill the body, but are not able to kill the soul: but rather
fear him which is able to destroy both soul and body in hell .
Being destroyed means they are Annihilated.
Psalms 37:20 But
the wicked shall perish, and the enemies of the LORD shall be as the fat of lambs: they shall consume;
into smoke shall they consume away.
Perishing and being burned and being consumed into smoke means they are Annihilated.
This is just a small offering of what the bible actually teaches on this subject.
