@livinglava,
no. In the Issua formation and in the Flinders Hills are actually " masses of spheroid blobs" of what appear to be Archea type cells. (These exact forms appeared later around -3.2-2.8 Billion years ago as the single cell prokryotes (No nucleii)) life forms)
The entire areas of the micro fossils contain internal chemical "fossils " also, the residual organic compounds are made of high ratio C12 to C13 . These chemicals are often predecessors of nucleic acids called "T" NA
So, "life" as we define it by its seven aspects had been apparently attempted on earth not much after the earth (and the solar system, were formed). The 4 (maybe more) attempts at establishing life are separated from each other by distance and sedimentary time. The evidence is pretty good. I dont say its conclusive because we can only interpret evidence. but the evidence , as I said, is very convincing to science. (except the Fundamentalist "Creation Scientists" who are not bothered with facts and evidence)
