precambrian........... has the least evidence and is when lady gaga started off as a man and decided to eat her way to present time!!!!
The Precambrian Era is the longest era with the least amount of scientific information available. This is because so few fossils have been discovered.

The Precambrian era is the longest geological era, spanning from about 4.6 billion years ago to 541 million years ago, but it is also the era with the least amount of detailed information available due to the lack of well-preserved rocks and fossils from that time period.
The Precambrian is the geological era about which we have the least information, as it covers an extensive period of time from the formation of the Earth to the beginning of the Paleozoic era, and much of the evidence from this era has been altered or eroded over time.
Era
The Cenozoic Era is the most recent geologic era and has lasted for around 65 million years, making it the longest era to date. During this era, mammals diversified and dominated the Earth's ecosystems.
The earliest era of prehistory was also the longest. The Stone Age lasted from around 25,000 years to ago to about 5,500 years ago.
The Cenozoic, which began 65 million years ago, and includes the present times.
Precambrian Era.

I wouldn't normally answer a question like this because separating our common era out like this is ludicrous. This is clearly the "plastic" age/era. If you want a quaint little answer how about the "amount information available to the populous and degree of interconnection between interpersonal networks". Or "the information era is an extension of the global" or... you get the idea. I'm a clever so-and-so answer: The speed of information transfer both node to node and more importantly in distribution from the corporate and special interest group media.
The longest era in geologic time is the Precambrian era, which lasted from about 4.6 billion years ago to 541 million years ago. It encompasses about 90% of Earth's history and is divided into several eons, including the Hadean, Archean, and Proterozoic.
