This article comes from the Universe Today archive, but was updated with this spiffy video. How old is the Earth? Scientists think that the Earth is 4. Coincidentally, this is the same age as the rest of the planets in the Solar System, as well as the Sun.
Radiometric Dating and Creation Science
So how did they support evolutionary theory before these discoveries? The main way scientists have supported the Theory of Evolution throughout history is by using anatomical similarities between organisms. Of course, there is always finding traces of long-extinct organisms that can also give a good picture of how a species changed over time. Traces of life from the past are called fossils. How do fossils lend evidence in support of the Theory of Evolution? Bones, teeth, shells, imprints, or even entirely preserved organisms can paint a picture of what life was in time periods from long ago. Not only does it give us clues to organisms that are long extinct, but it also can show intermediate forms of species as they underwent speciation.

Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.
Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long.
