Yes, you're right of course. But clearly the few generations of the "antibiotic era" have had a much larger effect on the bacteria than us. We used antibiotic technology to "evolve" resistance to bacteria. Bacteria responded much more rapdily than we could have naturally and is now a different organism than what our grandparents had to contend with. Now our technological "evolution" is unable to keep up with natures and we face a new threat not an old one. One we helped to create.
