Not correct, the data on earth that is reliable is based on carbon ratios, which are a far better hallmark. The older morphological stuff, while fun, is really just speculative, still.

Not for origin of life, no. We’re talking >3gy. These fossils are rocks, not biomaterials. Isotopes of trace decay products in the rock itself are used to age it, as is done with other geologic samples.
