Well, assuming they made no scientific mistake, and a living thing lived for 24,000 years, or came back to life after being frozen for 24,000 year... is this meant to be about the idea that deceased human beings might be frozen (they are being frozen) and brought back to life in the future?
I've always thought this idea was macabre, and I do not believe it is possible or will ever be possible.
Imo, these matters or only decided by God (or by the Universe, if you like).
