“We know the Earth’s billions of years old because of radioactive decay.”

“Well, how do we know the decay rate hasn’t changed?!”

*facepalm*

I have a creationist up at work that argues - and he got this from a book - that the radioactive elements we measure in rocks to determine their age may be seeping in and out over the last 6000 years so we can’t be sure how old the rocks actually are.
