Can we return after death?

The model for cloning a person and then, transferring memories to the new body was originally for interstellar spaceflights. The idea was to increase the lifetime of the crew by cloning the crew. And then, transfer skills and other things, that they have to the new body. The main question is: are those clones the same people as their predecessors?

Highly advanced technical instruments with biotechnology make it possible to clone people. But is that cloned person the same as its ancestor? That is a big question. If we make a clone and try to transfer all memories to that new body, we are facing one interesting thing. The neural network in our brains is not advanced enough. And that means the difference between the number of neural connections between children and adults is big. 

So we can say that the next body that the EEG gets is different than the first one. In this model, we are facing the idea that the memories stored in the EEG are the personality. And personality is the same thing as the person itself. But our experiences. Are modifying our personality. But the problem is that if we want to multiply the person, we must make a copy of the person's body. 

And then transfer to memories that person has to that body. There we are meeting one problem. There is a large number of neurons in the human neural network. 

There is also a large number of connections between those neurons. Those connections are making virtual neurons by connecting neurons in the human nervous system. And every single neuron handles one little memory unit. So making precise accurate copies of human memories require that all memories in the brain will copy. And transferred by using precise accuracy. 

But the biggest problem is the brain's ability to receive information. The number of neurons and their ability to create virtual connections is limited. Making human clones is possible. Those clones are embryos so they advance like "normal" embryos. 

Transferring memories to that new person requires that the person's nervous system is advanced enough. Theoretically, we can make a bio tank where those clones can advance and grow. The muscle-electric stimulation makes it possible to keep their muscles in good condition. 

But if we would grow those people or clones we must keep them in that tank for tens of years. Making that kind of thing in real life requires that the team can create adult clones. And that thing is impossible or at least very difficult to make. That thing requires that cells can cleavage very fast. And keep their genetic structure the same.
