Can someone tell me how old the earth is?

Answer 1

The formula for the formation of stars and galaxies is about to change with the confirmation of Dark Energy and Dark Matter. which have a effect on the their formation and how large the are.
But since we are in one of the arms of our galaxy. One would assume that the arms cooled first as they are farthest from the hotter center. So far the best guess is that the planet started forming 6 billion yrs or more ago.

Answer 2

It's based on several things:

1) dating meteorites. When we find a meteorite from this solar system that has a similar composition to earth, you get many young ages, but the oldest and most common date to 4.6 Ga (billion years).

2) isotope trends. When you look at certain radiogenic isotope ratios that change with time, like Rb/Sr or U/Pb, you find that many rocks with differnt ratios of many ages form a line, and the line traces back to an origin of 4.6 Ga as well.

The oldest life is 3 1/2 Ga, the oldest rock is about 4 Ga, and the oldest date ever found is on the highly durable mineral Zircon from Australia, it's date is 4.2 Ga. So, there is no direct method, it is based on inferences. However, many different inferences lead to the same number 4.559 Ga (to be specific).

You would have to throw out everything we know and love about Geology to accept a young earth view. When you look at the Grand Canyon, how can you say that only took 6000 years to form?

Answer 3

The oldest rock found on planet earth aged approximately 4.4 billion years before present. Hypothetically, it took 3 million years for the Zircon to form (rocks have certain amounts of time to form), therefore the earth is approximately 4.7 billion years old.

Answer 4

Roughly 4.6 billion years old. There are fossils that can help determine the age of the earth. Before there were tree's, used as fossils, there were single celled organisms that were buried in sediment from crazy storms when the earth was being created. There is a trace ( "tracks") of a worm type organism that dates back to about 4.2 billion years ago. Spoken from a true Paleontologist.

Answer 5

About 6000 years old.
Most dating methods indicate that the earth and universe are young.
For example:
The amount of salt in the sea.
Coal contains carbon 14.
Too much helium in rocks.
The decay of the earth's magnetic field
Lunar recession.
The existence of short-lived comets.
etc

The evidence of vast age does not stand up to scrutiny. For example radiometric methods have dated rock known to be just a few years old from Mt St Helens, as millions of years old!

Answer 9

I dont know, but compared to the time dinosaurs spent on the earth man has not even put a dent in that with the time we have been here. Millions id say
