Where in the Bible can we find the correct assumptions and good science to find the actual age?
God said that he will keep some things to himself such as the age of the Earth and universe. Thus, we will not know the exact age using science. We will have to make some assumptions, too. One method assumes that the six days of creation presented in Genesis 1 were literal 24-hour periods and that there are no gaps in the chronology of Genesis. The years listed in the genealogies of Genesis are then added to get an approximate time from creation to certain Old Testament figures. This gives us around 6,000 years for the age of the Earth.
We also had radiocarbon dating of coal and diamonds by RATE since C14 still remained. That showed a young Earth around 48 to 50,000 years old.
Radiocarbon in Diamonds Confirmed
How old do you believe the Earth to be and why?
God said that he will keep some things to himself such as the age of the Earth and universe.
Where did he say that?
Why does that mean that some rocks aren't billions of years old?
