answer... its from stress silly...stress can age people and environments prematurely..people can buy face cream but the earth must endure the hardships and show the wear and tear because after only 6000 years of existence how could it possibly know how to heal itself...
and besides that, anything that shows the earth being older than the age the fundies want to assign is just the devil at work trying to confuse them and their intelligence. as well as science trying to trump the rule of god..
hows that for an answer? now if only i believed it...they could say look... another successful conversion... pass that man the donation plate please and we dont want to hear a sound as you give your gift to god via our mega church with the tax deductible status.(hint- no change just bills and ideally 10% of your gross earnings this last pay check)..thats what its really about... pimping redemption using fear and prejudice to keep the cash flow positive...
