Walk 4.6 billion years of Earth's story in one scroll — Hadean to Holocene, an era per hall, with an Earth-in-one-day clock, jump-chips and a catalogue-numbered plaque for every exhibit...
Dated on the standard geological time scale (ICS). Exact figures vary by a few percent between sources — these are the accepted central estimates. Oldest Earth minerals ≈ 4.40 Ga (Jack Hills zircons); Earth itself 4.54 Ga. First life and the earliest fossils remain open scientific questions, and are labelled as such here.
