We measure distances in the universe using algorithms, so even if radiometric measurements were off to the extent that creationists believe, the universe is still as old as we believe it to be. The mathematics used for determining distance between stars can measure distance with over 90% accuracy. We could be off by a billion years or so, but it wouldn't be reduced down to thousands of years.
"In our youth, we lacked the maturity, the decency to create gods better than ourselves so that we might have something to aspire to. Instead we are left with a host of deities who were violent, narcissistic, vengeful bullies who reflected our own values. Our gods could have been anything we could imagine, and all we were capable of manifesting were gods who shared the worst of our natures."-Me
"Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all of which may be guides to an outward moral virtue, even if religion vanished; but religious superstition dismounts all these and erects an absolute monarchy in the minds of men." – Francis Bacon
