My opinion is that there was more Earth one billion years ago because of the ice age. I don't know if I'm right because I'm only a 6th grader.
The sun will not get big enough to engulf the earth for around 5 billion years. Even then the earth may be spared. However the sun will gets about 10% more luminous every billion years. Thiss will cause earth's temperature to rise to a point where all liquid water will boil off. This will happen in approximatly 1 billion years.
The Earth is estimated to be around 4.5 billion years old and is expected to remain habitable for several billion more years until the aging sun expands and engulfs it in its red giant phase. The Earth's longevity will depend on various factors such as geological processes, climate stability, and cosmic events.
Most scientists agree that the Earth and our entire solar system is about 4.5 billion years old. To the extent that there are disagreements as to the age of the Earth, the disagreements are in the decimal places. Some argue for 4.5 billion; some claim 4.6 or 4.7 billion years is more likely.
The Proterozoic eon was the third eon in Earth history. It lasted from 2.5 billion years ago to 542 million years ago. Therefor, the Proterozoic was nearly 2 billion years long.Read more: How_long_did_the_proterozoic_era_last
2 billion years ago, simple unicellular organisms such as bacteria and archaea were the dominant life forms on Earth. These organisms laid the foundation for more complex life forms to evolve over time.

No. The current best estimate is about 4.6 billion years.

1 b.C Nope, it wasn't.
the earth
There are significantly more gallons of water on Earth than there are people. The Earth's total water supply is estimated to be about 332.5 million cubic miles, which translates to approximately 1.3 billion trillion gallons. In contrast, the global population is around 8 billion people, making the ratio of water to people overwhelmingly in favor of water.
The same amount of water that has been here since the beginning of earth is here now and will always be here, with a few exceptions. 1. Asteroids and meteors crashing in to earths atmosphere will bring in new water. 2. Water leaving earth by going into space with satellites, rockets, space ships etc, will decrease the amount of water on the earth. 3. But, the biggest exception to this stament is in 5 to 10 billion years when the sun becomes a red giant and engulfs earth there will be no more water on earth because there will be no earth. So I guess the answer to your question really is in 5 to 10 billion years when the sun blows up.
we actually dont know how many more years the earth will live all we know is that the earth can sustaine life for about 2.6 billion more years . hey but dont worry we probaly wont be around when that happens
The Earth is 4.5 billion years old. Life has been around for 3.5 billion years. Complex life forms originated about 500 million years ago. There is no telling if/when life will cease to exist on Earth or if/when it will be destroyed in space.
* 3.5 billion years ago the first life arose: prokaryotic bacteria * 1.5 billion years ago eukaryotic cells arose Therefore, prokaryotes were present on earth for 2 billion years prior to the emergence of eukaryotic life.
Earth is 4.5 million years old. Solar system is far more older than it.
The Earth has more water than land area. The Earth's estimated total volume of water is 1.386 billion cubic kilometer or 333 million cubic miles.
