The first organism appeared during the Proterozoic period. It is estimated that the first organism appeared between 2.5 and 3.8 billion years ago.
No, the Mesozoic Era is not the first geological era. It is the era that followed the Paleozoic Era and preceded the Cenozoic Era in Earth's history. The Mesozoic Era is known for the age of the dinosaurs and lasted from about 252 million years ago to 66 million years ago.
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.
We are currently in the Quaternary Period of the Cenozoic Era.
We live in the Quaternary period, which is part of the Cenozoic era.
The geological events in the Mesozoic Era include, but are not limited to...The breaking up of Pangaea.The great meteor that hit earth destroying the dinosaurs
The oldest geological era is the Precambrian period. It is the period of Earth's formation, as well as the origin of the first single and multi-celled organisms.
During the Archean Eon life started and was dominated by one-celled prokaryotic life forms. Eukaryotic one-celled organisms became dominant in the Proterozoic Eon. Multicellular organisms ruled the planet during the eon known as the Phanerozoic.

No, the Mesozoic Era is not the first geological era. It is the era that followed the Paleozoic Era and preceded the Cenozoic Era in Earth's history. The Mesozoic Era is known for the age of the dinosaurs and lasted from about 252 million years ago to 66 million years ago.
The first organisms evolved during the Archean Eon, which occurred from approximately 4 billion to 2.5 billion years ago. This era was characterized by the development of simple, single-celled organisms like bacteria and archaea.
