To determine the most ancient type of life on Earth from the given options—fungi, protists, prokaryotes, and eukaryotes—we need to understand the evolutionary timeline of these organisms.

1. Fungi: These are eukaryotic organisms that evolved after prokaryotes and are not the oldest.
2. Protists: This group also includes eukaryotic organisms but evolved after prokaryotes.
3. Prokaryotes: These are unicellular organisms that lack a nucleus and include bacteria and archaea. They are believed to have appeared very early in Earth's history, around 3.5 billion years ago.
4. Eukaryotes: This category includes organisms that have complex cells with a nucleus. Eukaryotes are more recent in evolutionary terms compared to prokaryotes.

Final Answer

The most ancient type of life on Earth is prokaryotes.
