I thought you go to heaven when you die? At least that’s what everyone believes. Apparently these folks died and didn’t go anywhere which is exactly what the Bible says. We sleep until that day when Jesus returns.
The doctrine of an immortal disembodied soul...another lie from Rome and most believe it.
2 Corinthians 5:8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
So we have the example of Moses and Elijah who aren't sleeping waiting on the second coming of Jesus.
And 2 Corinthians teaches that to be absent the body is to be present with Christ.
They were not dead....yet! They were very, very close to death.
And there is NO soul-sleep. Unless you think Jesus is a liar. Luke 23:43
Neither is there a Purgatory, but there was a place called Hades and Abrahams’ bosom, before Jesus lead the old testament believers to paradise (He did that during the time after the cross, and before he rose)
The problem with your argument is that no one here actually froze to death, despite the misleading headline. "when the cells really freeze completely, they undergo a crystallization process and become glass-like crystals. In this process they are irreparably damaged. "When the cells thaw after this process, all that is left of them is a mass of pulp," explained Dr. Alvin Merendino. This is a main reason why it’s currently impossible for doctors to freeze people and bring them back to life a few years later. - https://www.jpost.com/health-and-wellness/meet-the-woman-who-froze-like-a-lump-of-meat-in-the-freezer-and-survived-679417
Secondly, there are many testimonies of those who were "dead" including atheists, who had NDE's.

Thus your argument is countered by such.
What matters is what the Scripture best reveals. In brief.
Do you also believe that a dead body should not be cremated??
