Presentism

Only present things exist; past and future things do not.

What it claims

Presentism includes only present objects and events in its ontology. Dinosaurs existed but do not exist now; future people do not yet exist. It gives objective significance to the distinctions in McTaggart's A-series and treats temporal becoming as real.
