The earth is about 4.54 billion years old. This is not a theory but is a scientific fact. The science behind this fact is not that difficult to understand. Estimates on the age of the earth come from the radiometric dating of materials (rocks) to discover the amount of radioactive decay that has occurred since the materials being "metered" were sequestered inside the rock.
See the related question on uranium-lead dating. It is fairly easy to read and makes it easy to "connect the dots" and get an understanding of the ideas.
The most recent data indicates an age of 4.567 billion years.

Age of earth can be determined by?
Scientists determine the age of Earth through radiometric dating of rocks, meteorites, and lunar samples. This method measures the decay of radioactive isotopes in these materials to calculate the Earth's age, estimated at around 4.54 billion years.
What is a approximate age of the earth?
The Earth is estimated to be around 4.5 billion years old. This age is determined through radiometric dating of rocks and meteorites, as well as other geological evidence.
What is calculated age of earth?
The estimated age of the Earth is approximately 4.54 billion years old. This age is determined through radiometric dating of rocks and meteorites, which provides insight into the formation of our planet.
How many years as earth existed for?
Earth is estimated to be around 4.5 billion years old. This age is determined through radiometric dating of rocks and meteorites.
Who made the calculation regarding the age of the earth?
The calculation regarding the age of the Earth was made by scientists using methods such as radiometric dating of rocks and minerals. By measuring the decay of radioactive elements in these materials, scientists have estimated that the Earth is approximately 4.54 billion years old.
What percentage of the universes history has earth been around?
The age of the Solar System is estimated to be about 4.568 billion years; Earth is almost as old - estimated at 4.54 billion years. The age of the Universe is estimated to be about 13.798 billion years. Thus, the ratio is about 33%.
Age of earth and other planets?
It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.
