Pre-Cambrian Time Period
The period of Earth's time that would be considered longest is the Precambrian Era.
The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.
The geological time scale is the history of the earth. This is in the eras period and epochs.
