Is the earth millions of years old or thousands of years old?

Answer 1

The earth is BILLIONS of years old. That's 4500 Million years old , (about).

People think know this because of four ways of thinking about it.

1. We know about how old the sun is.

Think of a soda with ice. when we start drinking theres plenty of soda and a the ice is frozen and the soda is cold, when the soda gets "older" it is more watery because the ice has all melted, when the soda gets really "old" the soda becomes flat and doesn't taste good.

It's kinda like that with the sun, we can see other stars, some that are young and some that are old and when we look at them all we can know the sun is about 4.5 billion years old based on how it behaves.

Stars are also a little bit like people in how they behave. Very young sun-like stars are bright and white or yellow and very active. Adolesent stars are not as active but are still bright and usually yellow or light orange in color. Middle age stars are orange and not quite as active. Old stars are darker colors of orange and even less active,and may start to get fatter and very old stars will grow bloated , turn redish and then become more dim and evenually end up becoming nurserys for other stars or planets after they die.

We think the earth formed at the same time as the sun, so that is about 4.5 billion years ago.

2. Some elements on earth "decay" at a certain rate, think of it like a rusting tool in a shed or work area. One of the metals, Uranium decays over billions of years , almost all of the Uranium on the earth is of the same "decaying" age. That age is about 4.5 billion years ago. Oxygen and other elements have other "decay" rates and these also tend to support the fact that the earth has had oxygen in the atmosphere for about 3 billion years.

3. We know the earth is old because of fossils , some fossils are of shells of sea animals that are very simple. Some of these shells are found on the highest mountains in the world. So if we say these shells were once deep in an ocean "how often do earthquakes move this mountains" and "how much does the mountain move up or down up each time", if we then say ok "we've been here watching this mountain for 200 years and there were two earthquakes and each earthquake moved the mountain 1 inch. How long would it take to move 100 miles and 3 miles up.

By answering questions like that we can figure out how old certain mountains are, by doing this all over the earth the oldest mountains/rocks are in Australia and Canada and they are were formed a little less than 4 billion years ago.

4. We think the moon formed from the earth being hit by another planet about the size of the planet mars, and we think that this happened about 4 to 3.5 billion years ago based on how far the moon is moving away from the earth and the incline of the earth and the moon.

Some religions, notably the evangelical movement in the US, believe the earth was formed by God in 6 days. They figure based on the Bible backwards from when someone dies or was born backwards from Jesus , to King David, to Noah, to Adam and Eve and based on that math the Earth is only 6000 years old.

This is not supported by any scientists as a good, reasonable date as the planet's surface is too large and would still be mostly molten rock if it was only 6000 years old and there would be no oceans or life just a big molten radioactive lava ball in space like a red hot bigger version of the moon...

Other religions say that the earth was the result of a giant fight amongst the Gods and almost every society of man has what is called a "creation myth" which is how primitive people explain good questions when they don't _know_ or can't figure out the answers.

Answer 2

The age of the Earth has been known reasonably well since the 1950s, when geochemist Clair Cameron Patterson of CalTech determined it to be 4.550 billion years +/- 70 million years. This age was based on isotopic dating of 5 meteorites and a representative sample of modern Earth lead from a Pacific deep-sea sediment, all of which plot along a linear isochron on a graph of 207Pb/204Pb versus 206Pb/204Pb.

For this they had to build (the first) sterile lab because of the lead poising of gasoline became all samples contaminated in previous tests.

After months of precise measurings the team agreed on 4.550 million years, 45 years later that's where the number still stands. The consensus on the age of the Universe is now at 13.9 billion years. Although, of course, this one we may never know.

Answer 3

complicated technology is all i will circulate with because of the fact is verifiable and that i does no longer be waiting to submit those words have been it no longer for it. Our photograph voltaic gadget is anticipated to be some 4.6 billion years previous. The "youthful earth" perception of many non secular individuals is unsupported by using technology regardless of the undeniable fact that it would not marvel to locate numerous espousing it as nicely as numerous different ridiculous innovations. background demonstrates how relatively stupid maximum folk of humanity has been and nevertheless is. this remains a very primitive planet--cosmic-sensible

Answer 4

Maybe a categorical list with pointed mathematics:

4.6 billion since Birth in terms of shape, forces,
resources, rebirths, dormancies, ages of sleep
3.3 billion years in the same solar age
3.0 billion years in the same rings age
2.1 billion years in the same gravities
175 million of evolution
60 million of same land masses
20 million same orbit paths and interactions of nature
2 million since man walked and talked
250,000 since the first domestic attempts to farm
190,000 since the first educational fomula under God
100,000 since the first Babylonian satellites
25,000 since the Egyptian empires
5,000 since the trade and peace of missionaries
Takes a long time for this state of Blessings to confirm eden.

Answer 5

Millions of years it is estimated that earth has around 4.5 billion years

Answer 6

well scientist think that the universe is about 11-15 billion years old therefore I guess that the earth is near on million / billions of years old!

Answer 7

4.5 billion years is right. That's 4500 million years. I have no idea where the first two posters got their figures from.

Answer 8

Millions. Fossil evidence as well as age of rocks are definite .

Answer 9

most scientists agree the earth is estimated 4.5 billions yrs old. though the oldest rocks are dated to be 3.8 to 3.9 billion.

Answer 10

The age of earth according to science through the calculation of the half-lives of certain substances, is 1 billion years.

The age of the earth according to the Holy Bible through the genealogies of mankind, assuming earth and man was made by God(which I believe), is thousands of years old.
