Although antibiotics are literally lifesavers, assisting our immune systems to defeat some very nasty infections, many infections (fungi and bacteria) have evolved to resist and become immune to the antibiotics and antifungals. They've done this very quickly as humans count time but perhaps not as bacteria and fungi count time.
One reason for this problem is that people across the world (this problem is evidently most acute in South Asia) have overused antibiotics and antifungals in a wide variety of circumstances. So we're seeing more of these organisms shrug off our best attempts at killing them. It's as if prisoners started developing immunity to small arms fire. Such a thing would be an unwelcome surprise to prison guards tasked to stop breakouts.
Check out the fascinating nine minute video below which explains the dire situation we're in and how worse may be yet to come. As pointed out in the video some other reasons that this situation exists include the requirements of globalized capital and an unnatural food supply chain. There is nothing supernatural here but this is nonetheless a very real horror show.
