For example, a worldwide flood would uproot and bury preflood forests.This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.When creation scientists studied granite samples, they made interesting discoveries.They concluded that the helium in the rock was 100,000 times more plentiful than it should have been if the rocks were really 1.5 billion years old.

They concluded that their findings are consistent with an Earth that is about 6,000 years old.Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.With less carbon-12 to dilute the carbon-14 continually forming from nitrogen in the upper atmosphere, the ratio of carbon-14 to carbon-12 in the atmosphere would increase.However, for the last 3,500 years, the increase in the ratio has been extremely slight.
