In the 1600s, an archbishop in ireland calculated that the earth was only 6,000 years old. what do we know now about the earth?
1. the archbishop was correct
2. the earth is significantly older than 6,000 years
3. there is no way to tell the age of the earth
4. it’s only a little bit older than 6,000 years

The correct answer is 2. The Earth is significantly older than 6,000 years.

Explanation:

The Earth formed approximately 4550 million years ago and life arose about a billion years later. It is home to millions of species, including humans, and currently the only astronomical body where life is known. Atmosphere and other abiotic conditions have been significantly altered by the planet's biosphere, favoring the proliferation of aerobic organisms, as well as the formation of an ozone layer that together with the Earth's magnetic field blocks harmful solar radiation, thus allowing life in the Earth. The physical properties of the Earth, geological history and its orbit have allowed life to continue to exist. It is estimated that the planet will continue to be able to sustain life for another 500 million years, since according to current forecasts, after that time the increasing luminosity of the Sun will end up causing the biosphere to die out.
