>> This week's "helpful YEC missive" from AIG says:
>> "Q: Doesn't it take millions of years for coral reefs to form?

Error #1: The Bible does not say that the Flood occurred about 4,500
years ago. Adding up numbers in genealogies can give you a number
close to that, but the Bible itself makes no such assertion.
>> At one of the Barrier Reef's underwater observatories great
>>clumps of coral are already growing on the large anchor chains! <<
Not a very good quantification. Besides, the corals on the ships at
Truk (sank during WWII) are probably bigger, if they want a more

>> Anyone know the obvious answer to this one?<<
The most obvious answer is that the reef does not consist of a single
branch contantly growing straight up at its maximum rate.
180*12*2=4320; not knowing how much over half an inch limits more
precise calculation, but even under their totally unreasonable
assumptions, they are barely able to fit it into their time
framework. If coral ever grows at an angle, slows growth (e.g., due
to inadequate food, crowding, putting energy into reproduction
instead, or dying), gets broken or eroded, or otherwise fails to
match this optimum, then the margin of safety is gone. The entire
reef does not consist of a single species, either, and deepwater
corals are generally very slow-growing.
Again, they are presenting their own claims as Biblical truths.
