What if we learn to read human brains down to the most intricate details?

What if we learn to record, in detail, every action that occurs within the brain, every synapse firing, every cell interaction, every memory?

What if if all of this data could then be stored on a computer and used to re-engineer a new, identical brain?

What if this brain could then be put into a new body, thus creating a new version of us when we die?

What if we knew for a fact that there was nothing after death?

What if we gain the ability to live forever using this, or some other mind transfer technique?

What if we then discover another civilization on another planet, who is still too primitive to save minds, and who still believes that death is natural and essential?

What if we then engineer a situation, for example we send swarms of microscopic probes to their planet to monitor, transmit via microscopic satellites, and then record their minds on our computers?

What if we can then use this data to re-engineer the brains of these people back on our planet so that when they die they can be resurrected?


Would we?

More to the point, is there a civilization already out there that is doing this?
