Radiation from the sun strikes the atmosphere of the earth all day long.This also means that plants and animals that lived in the past had less C-14 in them than do plants and animals today.Just this one fact totally upsets data obtained by C-14 dating.There is more C-14 in the atmosphere now than there was 40 years ago.This would prove the earth is not yet 30,000 years old!
