140,000 years ago, Earth was in the midst of an ice age, with parts of the northern hemisphere covered in thick ice sheets. Human ancestors, such as Neanderthals and Homo sapiens, were evolving and adapting to the changing climate and landscape. The planet's ecosystems were vastly different from today, with diverse megafauna roaming the Earth.
Life is estimated to have first begun on Earth around 3.5 to 4 billion years ago. This early life was likely in the form of single-celled organisms in the Earth's oceans.
The Earth was formed 4.567 billion years ago from material accreted around the newly formed Sun.
A trillion seconds ago was about 31,688 years ago. This roughly places us in the Upper Paleolithic period of human history, when the first cave paintings were being created and early human societies were developing.
THEY THINK about 3.9 billion years ago (: 4.4 billion years ago(:
Perhaps you mean 200 million years ago? This supercontinent was Pangea.
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
Viking live life
Dinosaurs died
Billions of years ago when the Earth was young. There was no one there to experience it, though, as there were no animals on Earth, yet.
About 3.8 billion years is about the age of the oldest firm evidence of life on Earth.
The dinosaurs died.
Earth did not exist 65 billion years ago. However 65 million years ago an asteroid collided with Earth, triggering a mass extinction even that wiped out a wide variety of organisms, including the dinosaurs.
In 1900 years Ago
it shaped the moon
Earth formed approximately 4.5 billion years ago, not 50 billion years ago or 5 billion years ago. This age estimate is based on radiometric dating of meteorites and rocks on Earth.
About 3.8 billion years is about the age of the oldest firm evidence of life on Earth.
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
