Topic: Radiometric Dating and the Geological Time Scale

Figure 2. How relative dating of events and radiometric (numeric) dates are combined to produce a calibrated geological time scale. In this example, the data demonstrates that 'fossil B time' was somewhere between 151 and 140 million years ago, and that 'fossil A time' is older than 151 million years ago.

Abiogenesis - Wikipedia Abiogenesis, or informally the origin of life, is the natural process by which life arises from non-living matter, such as simple organic compounds. The transition from non-living to living entities was not a single event, but a gradual process of increasing complexity that involved molecular self-replication, self-assembly, autocatalysis and cell membranes.
