Archeology

[Lanell]

The study of whether or not there is a past; and if [so what] constitutes the past.
Also called [phenomenology] (self-annihilationism), [extinctionism], and artifactualism.
Incorrectly called annihilationism. (Annihilationism points in time forward.)

[Gregory]

the scientific study of [historic] or [prehistoric] peoples and their cultures by [analysis] of their artifacts, inscriptions, monuments, and other such remains, especially those that have been excavated.

[Ernesto]
