Hello my little Dost,
Even though we have written on the same topic, but you have written a story, right now I have only seen it superficially, but after giving this answer I will read it and there will be a separate discussion on it.
The research you have read about can be dangerous, if they create dinosaurs of extinct species then what will happen to us humans. By the way, I have also read that some very rich people have got many clones of themselves made. And they are their exact look alikes and replicas.
All this is beyond my imagination.
Be happy, be cheerful, be healthy.
