If the earth is no more than 6,000 years old, and the Flood disrupted ocean life 4,300 years ago, can coral reef “ages” of tens of thousands of years be correct?
The suggested rates of .003–3.1 inches/year (.08–80 mm/year) are far less than actual recorded rates of growth based on soundings, which reveal annual growth rates of 11–16 inches (280–414 mm). With the right amount of light and water temperature, coral can grow much faster than some have suggested. With these growth rates, even the largest coral reefs could have formed in the 4,300 years since the Flood.
