The Pleistocene epoch occurred between 1.6 million to 11,000 years ago. It is known as the ice age, because large sheets of ice covered much of the earth.

The Ice Age started in the Pleistocene era.
Pleistocene
This is the Cenozoic era, near the boundary of Quaternary and Neogene periods, and therefore near the boundary of the Pleistocene and Pliocene epochs. Please see the link.
Pleistocene
The horned gopher became extinct in the early Pleistocene era.
Humans are thought to have evolved during the Pleistocene era. This period began about 2.5 million years ago and lasted until about 11,700 years ago. It was characterized by multiple ice ages and the emergence of early human species.
The ice age occurred during the Pleistocene epoch, which lasted from about 2.6 million to 11,700 years ago.
If by "Common Era" you are referring to the era name system, then Christianity coincided with the beginning of the Common Era. In fact, the Common Era is also known as the "Christian Era" or "Current Era". The year 1 CE is the year in which a 6th century monk estimated that Jesus had been born when he created the Common Era calendar.
The Pleistocene epoch
Two million years ago falls within the Pleistocene Epoch, which is part of the Quaternary Period. The Pleistocene is characterized by repeated glacial cycles, where large ice sheets covered significant portions of the Northern Hemisphere. This era is marked by the evolution and spread of early humans and the extinction of many large mammals. The Pleistocene lasted from about 2.6 million to approximately 11,700 years ago.
They have been around since at least 300,000 years ago during the Pleistocene.
