I'm just saying that if you look in Revelation, they were souls first, and then they were alive again. It is not to say it isn't a resurrection, but I think there is more than enough to question.
Are you referring to the souls under that altar as if before they were born in regards to Revelation 6:9-11?
Revelation 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held: 10
And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? 11 And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.
Those souls are crying to the Lord to avenge the spilling of their blood on the earth and so that canot be the case.
Unless you wish to explain your comment further and what specific reference in Revelation you are referring to, I can only guess and explain why I disagree with that assessment if that was the reference you were referring to.
However, as a tot, I have been getting prophetic dreams and did not realize that they were prophetic dreams until years later when I was moved across several states with my family when that day I had arrived, I dreamt an event as it would happen the very next day and it did and I ask the Lord why did this happen and I got this impression in my mind saying "The stage is set, the characters are in place: the die is cast".
When I finally met that girl in my dreams, she is 12 years younger than me. I was a tot about 5 years old when I started dreaming about her and so I had dreamt her about 7 years before she was born.
In one of the series of dreams as a tot, I was in Heaven enjoying the Presence of being with the Lord in His Temple; and I heard voices of my family crying out, pleading with me to come back. The Lord was there and He showed me the Book of what I would be doing if I went back; and I saw the adult sins I would be committing and I did not want to sin against the Lord; I did not want to be separated from Him and I was grieved in my heart & spirit in not wanting to go back and that made my family plead all the more in anguish for me to come back. Then the Lord said "I will see what I can do.."
Not sure if that nightmare was prior to my waking up where I was about to be strangled to death in a freak accident by my own bed sheets. Both ends of the bed sheet were to the side of the bed as it was tied in a know around my throat. I found myself choking to death as I could not breath. I tried to dig my fingers into the knot to untie it but to no avail. Then I collapsed, praying silently for God to save me. Then I found myself able to breath when I had stopped struggling. And then proceeded to untie the knot.
The next day, my mother noticed my blood shot eyes and alerted my dad as I explained I had almost choked to death that last night. It would make sense that nightmare was prior to that event, but I cannot exactly recall if it was.
Getting back to the series of those prophetic dreams as a tot, the way those markers in my dreams fell into place as they came true as I did commit those adult sins and am still ashamed for committing them but the Lord has delivered me from them and is keeping me from them. All the markers identifying that girl as the one in my dreams also fell into place as she was not to marry me but another whose wife was attached to another for why he could not go back to her and this "priest" allowed the girl of my dreams to be with him.
There is more but there is no point to continue about the dreams other than that the initial dream had my mother waking me up in my sleep because she had thought I was having a nightmare when in fact I was having a wonderful dream of being with that girl that I love in Heaven... raptured? I hope in Jesus Christ so... since the firstfruits are not marrying nor given in marriage and so she would be like a beloved sister to me, but of course, His love in me for her would be the same for all my brothers & sisters & mothers in Heaven.
But I was so happy to see her there in Heaven safe in the Lord.

Really wished my mother had not waken me up.
So did we have an existence before we were born
or was that just the Lord showing me things to come and by my looking into that Book, is my seeing all the events including the ones regarding the girl I love with His love but played out in time as He dispensed it to me as a tot?
When I see Him face to face, I should know all things, but if that was what you were inferring to, having an existence before we were born, there is scripture that suggests it, but not really prove it.
Psalm 139:13 For thou hast possessed my reins: thou hast covered me in my mother's womb. 14 I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. 15 My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.
16 Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them. 17 How precious also are thy thoughts unto me, O God! how great is the sum of them!
Does that mean we had existence in the thoughts of God before we were born? I do not know now, but I am sure we will know later on.
But I do not believe Revelation 6:9-11 ( if that was the reference you were referring to in Revelation ) is about souls pre-existing when they are under the altar and crying for the Lord to take vengeance on those that spilled their blood on the earth but the Lord told them to wait instead.
Thanks for sharing.
