Single cell prokaryotes first appeared perhaps 3.8 billion years ago.
Scientists believe that the earth's atmosphere has been in existence for over 3.5 billion years. This is based on the fossil records that are found which date to so many years.
The earth has been around for a loooong time , and i were to right down the number of minutes the earth have been around, i would need A LOT OF paper.
They didn't come to earth they evolved here
The Earth completes a full orbit around the Sun once every year. The Earth has existed for approximately 4.5 billion years or so, which means that it has 'gone around the Sun' around 4.5 billion times.
earth is about 4 billion years old
eff the time in wich life first evolved on earth!!
2 Billion years
The Earth is estimated to have formed around 4.5 billion years ago. It gradually evolved from a hot, molten mass to a cooler, solid planet over millions of years.
The first photosynthetic organisms, cyanobacteria, are believed to have evolved around 3.5 billion years ago. These ancient bacteria were able to harness sunlight to convert carbon dioxide and water into energy-rich molecules, paving the way for the oxygenation of Earth's atmosphere.
By god!
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
Not at present. All life on Earth appears to have evolved here, and it's all related.
a. marine invertebrates b.land plants c.reptiles d.prokaryotes
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.
He thought the sun evolved around earth

Radiation has existed on Earth since its formation around 4.6 billion years ago. Natural sources of radiation, such as cosmic rays from space and radioactive elements in the Earth's crust, have been present since the planet's early days. Early life forms evolved mechanisms to cope with this background radiation.
