The age of the Earth is not known exactly. It's somewhere about 4.54 billion years old. But the ability to support life has been much shorter.
A fissure I think, been a long time since I did geography though
When Earth formed, it was initially composed of gases such as hydrogen, helium, methane, and ammonia. Over time, these gases gradually dissipated into space or were absorbed into the planet's interior. The gases released from the Earth's interior during volcanic activity contributed to the formation of the early atmosphere.
The Solar System is about 4.6 billion years old; the Earth formed around that time, and has been orbiting the Sun, and rotating, since then.Note that Earth's rotation has been slowing down over time, due to tidal forces, mainly from the Moon.
The Stars The Earth came third and moon came second Actually, yes the stars did come first, since matter had combined from the big bang, but the Earth and Moon are tied, since no one knows how the moon formed, we cannot assume what time they appeared.
For the traveller, the trip takes 1 year, travelling at 60% the speed of light (or 0.6C). This would mean that he will perceive himself as have travelled 0.6 light years (a distance of about 9.46x1012km). To calculate the time that has elapsed on Earth, you can use this simplified equation: Spaceship Time = Earth Time x sqrt[1-(v/c)2] Spaceship Time = Earth Time x sqrt[1-(0.6c/c)2] Spaceship Time = Earth Time x sqrt[1-(0.6)2] Spaceship Time = Earth Time x sqrt[1-0.36] Spaceship Time = Earth Time x sqrt[0.64] Spaceship Time = Earth Time x 0.8 Spaceship Time = 1 year 1 year spaceship = Earth Time x 0.8 Earth Time = 1 year spaceship / 0.8 Earth Time = 1.25 years Thus, after 1 year has passed for the person on the spaceship, 1.25 years have passed on Earth.
When calculated according to the 4.6 billion years since earth was formed humans have live in it 0.09 percent of the time.
it has been for 90%
The Earth never became round. It has always been round in shape since it was formed at the beginning of time.

Earth is thought to be 4.5-4.6 billion years old.
That there be enough of it for evolutionary processes to take place. Humans have trouble comprehending the deep time that has passed since the formation of the earth.
Humans span roughly 0.0044% (about 4 thousandths of one precent) of the time since the Earth was formed.
some time
Yes!!! It does it all the time; it is called 'light'.
One year is one revolution around the sun.
Although time is eternal the measure of time is not. The YEAR is undetermined since it is one of the first things that occurred on earth.
it was formed from extreme pressure for a long time under the earth.
