The beginning of Earth is generally considered to be around 4.54 ± 0.05 billion years ago. This is the estimated time when the Earth formed from the accretion of dust and gas in the protoplanetary disk surrounding the young Sun.

Here's a breakdown of what we know about Earth's early history:

* Formation: Earth formed through a process called accretion. Dust and gas particles in the solar nebula gradually collided and stuck together, forming larger and larger bodies. Over millions of years, this process led to the formation of Earth.

* Early Earth: Early Earth was a very different place than it is today. It was incredibly hot, bombarded by asteroids and comets, and lacked a stable atmosphere or oceans.

* The Hadean Eon: This period, from about 4.5 to 4 billion years ago, is characterized by intense volcanism, frequent meteorite impacts, and the formation of Earth's first crust.

* The Archean Eon: Between 4 billion and 2.5 billion years ago, Earth's first oceans formed, and life emerged. The earliest life forms were simple, single-celled organisms that thrived in the harsh conditions of the early Earth.

It's important to note that our understanding of Earth's earliest history is still evolving. Scientists continue to learn more about this period through research and analysis of ancient rocks and minerals.

Therefore, while we can estimate the beginning of Earth's formation, the exact details of its early history are still being pieced together.
