Only a fool would believe what you claim.
If the bacteria evolved into a new life form why then you’d have proof of macro-evolution. Which you clearly do not.
I am not saying that error prone DNA polymerase is going to change them from a bacteria to a non-bacteira - but it could, and no doubt has, led to different strains of bacteria from the same common ancestry.
What I am saying is that a bacteria under stress has a mechanism to INCREASE its mutation rate.
Now why do you think a bacteria under stress increasing its mutation rate would lead to better chances of survival?
Obviously the bacteria stress response is at odds with your view of mutations and what they can and cannot do.
Does this make you question your ignorant assumptions about mutations?
It should.
Where do bacteria “store” these mutations?
What is the evidence that large genome species go extinct due to mutation? Do you even have a single example?
Are you embarrassed by how badly your views line up with reality?
You should be.
