Dating creation for the creation by using ancient sources or records of mythological figures. Since Inachus was dated 400 years after the flood of Ogyges and that Ogyges himself was considered a Titan or a primordial Autochthon "from earliest ages", some ancient Greek or Romans dated the creation (beginning with Chaos or Gaia) only a few hundred years before Ogyges (2376–2050 BC). Most ancient Greeks, however, did not subscribe to such a literalist view of using mythology to attempt to date the creation; Hecataeus of Miletus was an early ancient Greek logographer who strongly criticised this method, while Ptolemy wrote of such
Expansion of the universe suggest that very early in the history of the universe, there was an inflationary phase where the metric changed very rapidly, and that the remaining time-dependence of this metric is what we observe as the so-called Hubble expansion, the moving apart of all gravitationally unbound objects in the universe. The expanding universe is therefore a fundamental feature of the universe we inhabit — a universe fundamentally different from the static universe Albert Einstein first considered when he developed his gravitational theory. In expanding space, proper distances are dynamical quantities which change with time. An easy way to correct for this
