Does radiometric dating prove the age of the Earth?

Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations. T he presupposition of long ages is an icon and foundational to the evolutionary model.

What is the basic principle of radiometric dating?

Radiometric dating is based on the decay of long-lived radioactive isotopes that occur naturally in rocks and minerals. These parent isotopes decay to stable daughter isotopes at rates that can be measured experimentally and are effectively constant over time regardless of physical or chemical conditions.

How do we know the age of the Earth?

Using radioactive dating, scientists have determined that the Earth is about 4.5 billion years old, ancient enough for all species to have been formed through evolution. 1 The primary dating method scientists use for determining the age of the earth is radioisotope dating.

How do Geologists use radioactivity to determine the age of rocks?

Instead, radioactive dating indicates that Earth is about 4.5 billion years old—plenty of time for evolution and natural selection to take place. [i] But as we show here, geologists do not use radioactivity to establish the age of certain rocks. They instead use selected radioactivity results to confirm what they need to see.

Does radiometric dating prove millions of years old?

Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations. The presupposition of long ages is an icon and foundational to the evolutionary model.

How is the age of the Earth determined?

The same techniques of radiometric dating have been used on those rocks. All the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample.

Does radioisotope dating prove the oldest Earth?

Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth. This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).

How do scientists measure the age of rocks?

We are told that scientists use a technique called radiometric dating to measure the age of rocks. We are also told that this method very reliably and consistently yields ages of millions to billions of years, thereby establishing beyond question that the earth is immensely old – a concept known as deep time.

Ask an Astronomer How do we know the age of the Universe and the Earth? (Intermediate) Scientists say that the Earth is 4.6 billion years old while the universe is somewhere from 10 to 20 billion years old. Is it true that in the 60s scientists spotted background radiation that they thought to be remnants of the Big Bang?

How old is the Earth?

Do Geologists use radiometric dating to determine the age of rocks?

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that.

Why is nuclear decay used to determine the age of rocks?

The nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful tool for determining the absolute age of rocks. Radioactive decay is the process by which a “parent” isotope changes into a “daughter” isotope.

When was geologic time measured based on radioactivity?

In 1905, the British physicist Lord Rutherford -- after defining the structure of the atom -- made the first clear suggestion for using radioactivity as a tool for measuring geologic time directly; shortly thereafter, in 1907, Professor B. B. Boltwood, radiochemist of Yale University, published a list of geologic ages based on radioactivity.

Can a geologist tell the age of an object?

Listen - most geologists can do the simple stuff, like - ‘if it’s in a rock layer under that other one, then the layer underneath is older’. We can ALL do that. But accurate ages? Take it to people who have the right tools, which are specialists.
