Pfft, c'mon you heathens, don't you know god can do anything? He obviously added all those fake tree rings to those trees to make you think they were older than they were. And the mountains? Well, they just LOOK millions of years old, there really only a few centuries old. Silly heathens. So what if it doesn't make sense, god can change physics around whenever he wants and reverse any evidence of it happening, AND plant evidence to the contrary at the same time!
And, of COURSE he would plant so much fake evidence that all points to the same fake conclusion! Don't you understand, he wants to test your faith because he LOVES you!! And, you'd better stop believing everything all the evidence points to and start believing what we say, real soon! After all, god talks to us and us alone (make sure to sign your checks, please, thanks) and you'll burn in hell forever if you don't stop your doubting ways!
