unknown life era
Etymology
'agnotozoic' originates from Greek, specifically the words 'agnostos' meaning 'unknown' and 'zoikos' meaning 'pertaining to life'.
'agnostos' and 'zoikos' combined to form the term 'agnotozoic', used in geological contexts to describe a period with no known life forms.
Initially, it meant 'pertaining to unknown life', but over time it evolved into its current meaning of 'relating to a hypothetical era with no known life forms'.
