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.
The oceanic crust is the outermost layer of the lithosphere of the Earth. Scientists have estimated that its average age is around 200 million years.
It's estimated to be 27%.
Geologists and other related Earth scientists have estimated the age of the Earth to be approximately 4.65 Billion years old based on a wide variety of scientific experiments and data.
Absolute age is the definite age of a fossil, while relative age is an estimated age according to the sediments and other fossils around the fossil.
There are over 7 billion people on planet Earth. The most populated countries on Earth include China, India, and the United States.
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%.
Scientists estimate the age of our Solar System to be around 4.7 billion years old. They base this on observations and light spectrometry of the Sun.
It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.
We don't actually know what year the earth was made. Or I don't know anyway.
