Whereas the twin is not real life, but just a scenario in the future. Inactive, not alive, just a shadow, a future.

They think it’s alive because compared to the current circumstances and current time here, the parallel nature is also sequentially.

Similarly this, in fact, parallel nature is a different scenario of our life path.
