The original dating of the rocks in which these stromatolites were found is a fascinating story in and of itself.

The discovery of the Earth's oldest rocks ( http://rsnr.royalsocietypublishing.org/content/63/4/381 ) deals with the isotope dating of these same rocks:

"One memorable day in 1970, we first analysed isotopically a sample of Amîtsoq gneiss (see above) sent to Oxford by McGregor, representing the oldest member of his sequence. We found that it had a more ‘unradiogenic’ lead isotope composition (that is, lower 206Pb/204Pb and 207Pb/204Pb ratios)7 than any terrestrial ore or rock lead ever reported previously. On any plausible terrestrial lead-isotope growth models, which were already fairly well understood by that time,,3 the analysed lead, and hence the rock, must be at least 3.7 Gyr old. By that time the gneiss had already become highly depleted in uranium (a common observation in strongly metamorphosed gneisses), so that radiogenic evolution of their lead from uranium had virtually ceased."

The layer is all that is left of the past civilization.
Squashed flat by time and rock. If they remove the layers above they will see a grid pattern of a city.... : )

There are no fossils that old. God created them 6,000 years ago when he created the Earth. He just made them look old so we would be confused. He also made the whole vast universe at the same time to test our faith.

We should assume these “fossils” are of non-biological origin until there is stronger evidence otherwise.

Surprisingly, the NYTimes has a much more balanced article on this claim.

.....that life on Earth emerged rapidly in the planet's early years.

Well they are right about something. Life emerged quickly. Five days is really quick, at least to us (a day is as a thousand years to God).

These finds are suggestive that a key variable for the abundance of life in the universe — it’s survivability in early unicellular evolution — is fairly benign, since the conditions of life that early in Earth’s geological history were not only harsh, but quite volatile.
