Explanation:
Archaea : oldest form of prokaryotes (single-celled organisms without a nucleus). Ancient bacteria; often live in extreme conditions.
Bacteria : all other forms of bacteria (i.e that are not under Archaea)
Eukarya : all eukaryotes (cells have a nucleus. could still be unicellular, though)
Humans, Animals and Plants are all under Eukarya.
A typical person won't ever encounter Archaea in their life, because they live in extreme environments.
The broadest classification of life used to be kingdoms. Domains were created in 1990.
Hope this helps :)
