    so where will the phage go after they killed the deadly bacterias? stay in our body forever? if they do stay in our body, we will basically be immune to these type of bacterias? and how will the phage survives in our body that long? will they start to kill us?

    Antibiotics are like plastic.
    When we discovered them, it felt like as if we'd found the cure to death itself and we started expanding its range of applications throughout our lifestyle.
    But no one realised that everything has a price...

    But if all the bacteria is killed eventually by the Bacteriophage, wouldn’t that mean that the phage would either disappear or evolve to consume our good cells/bacterias to survive? There really isn’t a shortcut...

    As you said, phages evolve.
    If we keep using them to save us they might start to see it as an easy opportunity to start killing some of our important cells, and it would be even worse than medieval times.

      Then our immune system fights them. We treat them like any other virus, make sure that there is always a safety net. However, they don't need human cells, due to the vast amounts of bacteria that is more than enough to reproduce itself.
