Period: PrecambrianAge: 2.4 - 2.2 billion yearsRegion: Michigan, USAThis fossil was unearthed in the state of Michigan, USA, and is an example resembling marble of stromatolitic materials belonging to when life first appeared on Earth. Marble is a metamorphosed form of limestone. The green color so attractive to the eye is the result of serpentine, which forms when there is a high level of magnesium in the limestone. 9Fossil stromatolites are colonies of cyanobacteria, the oldest known organisms. These bacteria that lived billions of years ago, seen fossilized among rock strata, have highly complex structures and are capable of manufacturing oxygen. The processes that these organisms carry out in their micro-bodies, too small to be seen with the naked eye, exhibit a perfection that today’s advanced technology is nowhere near approaching. Cyanobacteria, which Darwinists claim are “primitive early life forms,” make photosynthesis using sunlight and convert water into oxygen molecules as well as protons and electrons. The structures known as thylakoids they use for photosynthesis are located within the folds of the cell membrane. Thylakoids have special antennae known as phycobilisomes that collect light for photosystems. It is clear that such an architecture is not at all “primitive.”Considering both their structures and the processes they perform, these organisms, which date back 3.9 billion years, are not at all primitive, but have been highly complex ever since the moment they were first created.
