Yes, the last day. I really appreciate your post because I, myself, have posted the exact same thing several times in the past. There are a lot of examples that show the resurrection happens on the last day, and I argued that scripture does not specify the last day of something in particular, so it must be the last day of all days.
However, I've since come to realize that these verses all refer to the last day of the age, which was in 70 AD. Here's my logic:
1. The old covenant ended in 70 AD
2. The old covenant caused sin and sin caused death
3. There is now, no more death
4. If death has been destroyed, that requires all to have been resurrected
I don't think we can understate the importance of earth's transition from the old covenant to the new. It was our transition from night to day, from darkness to light, from death to life.
Revelation 22:5 says "there will be no more night". This was referring to death. There will be no more death. In the context of this analogy, we can understand that without night, we are now on the last day, because days only end when the night comes. And yes, Revelation 22:5 has already happened. We know this, because we know that death has been defeated, so there is no more "night".
About death , people still die.
They die everyday, millions of people are born, live a while, but they all do die.
Death being no more is at the end as death is the last enemy to be destroyed.
Since people still die today, the last enemy death has not been destroyed, therefore it is not the end yet.
Christ is the first fruits of those who have 'fallen asleep' in the Lord
Christ died, God raised Him up in a bodily resurrection
Believers who die in the Lord, their life is hidden with Christ in God, we were raised spiritually so that our home is now in heaven, we are no longer of this earth.
When Christ appears (second coming) we will appear with Him in our own glorified body, one like He has,
This Christ as our risen hope, has to do with our own resurrection, being give a glorified body like He has.
1 Cor 15
The Risen Christ, Our Hope
12 Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then Christ is not risen. 14 And if Christ is not risen, then our preaching
is empty and your faith
is also empty. 15 Yes, and we are found false witnesses of God, because we have testified of God that He raised up Christ, whom He did not raise up—if in fact the dead do not rise. 16 For if
the dead do not rise, then Christ is not risen. 17 And if Christ is not risen, your faith
is futile; you are still in your sins! 18 Then also those who have [
c]fallen asleep in Christ have perished. 19 If in this life only we have hope in Christ, we are of all men the most pitiable.
The Last Enemy Destroyed
20 But now Christ is risen from the dead,
and has become the firstfruits of those who have [
d]fallen asleep. 21 For since by man
came death, by Man also
came the resurrection of the dead. 22 For as in Adam all die, even so in Christ all shall be made alive. 23
But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming. 24 Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26
The last enemy that will be destroyed is death. 27 For “He has put all things under His feet.” But when He says “all things are put under
Him,”
it is evident that He who put all things under Him is excepted. 28 Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.

Obviously, we have not appeared with Christ yet as we do not have glorified bodies yet as we are still Hidden with Christ.
Colossians 2
11 In Him you were also circumcised with the circumcision made without hands, by putting off the body [
h]of the sins of the flesh, by the circumcision of Christ, 12 buried with Him in baptism, in which you also were raised with
Him through faith in the working of God, who raised Him from the dead. 13 And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses, 14 having wiped out the [
i]handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross. 15 Having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.
Colossians 3
If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God. 2 Set your mind on things above, not on things on the earth. 3 For you died, and
your life is hidden with Christ in God. 4 When Christ
who is our life appears, then you also will appear with Him in glory.

Now about the glorious liberation of the creation, that has also not yet happened. But it will when God makes all things new, new earth, new heavens, at Christ's return
Right now, still, the creation is subjected to futility, it waits for the revealing of the glorified sons of God in the new earth.
Creation fell, creation will be fixed, it is still a fallen world today. Evil terrible things take place on the earth today.
We DO NOT SEE it today but we hope for it with perseverance.
Romans 8
18 For I consider that the sufferings of this present time are not worthy
to be compared with the glory which shall be revealed in us. 19
For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. 20 For the creation was subjected to futility, not willingly, but because of Him who subjected
it in hope; 21
because the creation itself also will be delivered from the bondage of [f]corruption into the glorious liberty of the children of God. 22 For we know that the whole creation groans and labors with birth pangs together until now.
23 Not only
that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body.
24 For we were saved in this hope, but hope that is seen is not hope; for why does one still hope for what he sees?
25
But if we hope for what we do not see, we eagerly wait for
it with perseverance.
