i dont think anyone really knows for sure. probably like thousands of millions of years. unless it gets hit by a ginormus asteroid and explodes into teeny tiny peices!! lol

Scientists say that the Earth is about 4.5 billion years old. The oldest rocks that have been found are 3.8-3.9 billion years old. They actually think the Earth is 4.55 billion years old to be specific. Just to let you know i got it off  a website.

It should be habitable for another billion years unless we do something to deal with the increase in energy the sun is giving out.\n\nThe Earth should be destroyed after about 5 billion when the sun becomes a red giant (unless of course we remove some mass from the sun to make it last longer).  If it isn't destroyed by that then it'll last a very long time (not sure how long, could be until end of the universe however that happens) but it won't be very useful (except for materials).

The Bible is the Standard in Christianity. The Bible places the age of the earth about 6200 (+/-150) years, whereas evolution dates the earth about 4.5 billion years.  Evolution places death before sin. Dinosaurs died millions of years ago, but the first sin about occurred in the first 100 years after creation. These two will not add up.

I can't tell you exactly how long we've been in existence, no one can. But to answer your second query with the way things are going i think we have two more generations of life left in us before total extinction due to pollution, religous wars or anarchy. Sorry, have a nice day.

In around 4 to 5 Billion years when the Sun is swollen in its death throes before it collapses into star known as a white dwarf . In fact the whole Earth will be vapourised.\n\nIf you mean by your question when will it be destroyed environmentally, then that's upto the caretakers of this planet wether that is humans or some other species.\n\nOtherwise the Earth will always have an atmosphere of one kind or another until the Sun begins to die.\n\nJules

So let me get this right...  \nAdam lived 1/5 to 1/6 of the time the planet has been here?\n\nInsane and stupid is harsh.  I probably wouldn't go that far unless you insulted my belief that...  like somebody else said, there are written records from before 5000 years ago.\n\nThere are ruins of cities <not encampments of cave people, but actual CITIES> that are 10,000 years old.

Estimates range between 10 and 15 or so billion years, with most scientists thinking it is closer to 13-15 than anything else.

The moon is moving away from the Earth at about 3.8 cm per year.  At this rate, it is calculated that the moon will be far enough away from the Earth not to cover the sun in slightly less than 600 million years.

No one knows...yet. Give it time, like a few billion years.

Between 12 and 14 billion years.\n\nLearn more here:\n\nhttp://map.gsfc.nasa.gov/m_uni/uni_101age.html

The currently accepted estimate is 4.5 to 4.6 billion years old.  Radiometric dating of Earth rocks can't get us there because the surface of the Earth has undergone so much upheaval.\n \nInstead, moon rocks and meteorites are used to estimate the age of the Earth, because it appears that all of the solar system formed at about the same time.\n\nCarbon dating is of no use here; it only works for organic material and it can't date back further than 50,000 years or so. Long-lived radioactive elements such as uranium are used instead.

Good question. That's something I've actually been thinking about as well after constantly reading in the news about the increasing amount of hatred and how people are suffocating the planet. I really don't see it being too long before humans destroy themselves. Considering how long humans have been on the planet, it will be a relatively short time before we're gone.

The Earth is 4,570,000,000 years old, approximately; though many Creationists think it to be only 6000 "without proof otherwise" they are wrong: we have proven it using gravitational measurements of other planets, measurements of solar brightness over time, radioactive dating, continental drift, and many other factors. If you want to  force religion on people, don't do it in a SCIENCE forum! You will only cause heated debates and great offense from both sides.

It is estimated that the point of no return is about 10 years.\nOh yeah it's not "saving the planet" but keeping the climate stable for life as we have enjoyed  it for the past 100k years.

Greetings,\n\n4.5 billion more years until it swells into a red giant and engulfs Earth.\n\n-matt

How many years are represented in the number thitteen? Let my be more precise by adding Earth years to that question.
