It’s always interesting to see how the media distorts scientific material to make it more sensational. The front page of USA Today for March 2, 2017, carried a headline saying: “3.8 Billion-year-old Bacteria May Be Earth’s Oldest Fossils.” The article goes on to state as fact: “The bacteria lived near hydrothermal vents…” There are so many issues here that it would take several pages to point them all out, but the interesting thing is the actual discovery. Stromatolites are layered structures that may be produced by algae or bacteria, and some are ancient deposits, although others are still being produced today. I have seen these formations in the Gunflint Chert in Minnesota near a cabin owned by my brother. Those formations are circular and contain a mineral called hematite, an iron mineral that may have been a part of the biology of microorganisms.
This new find is an iron carbonate rosette that is circular and contains hematite. There is some evidence that it was formed near an undersea thermal vent. Since we see life around sea-vents today, it might be assumed the formation is of biological origin. There are chemical, non-biological processes that can produce similar structures. The problem with this kind of media headline is that it gives a false impression of how science works and what has actually been found. It may be that these structures were biologically formed, and they may be 3.8 billion years old. The Bible doesn’t date or describe bacteria and how God formed the ecosystem that would support humans on planet Earth. This same process may even be going on elsewhere in the universe, but it will take exhaustive research to verify or deny whether this is ancient life.
Real science does not announce possibilities as fact. The exaggeration of scientific discoveries does a disservice to science and makes modern day readers believe things as proven that are simply speculations. Stay tuned for what future study of these structures reveals as truth.
