--- How can one be certain that decay rates have been constant over billions of years? Scientific measurements of decay rates have only been conducted since the time of the Curies in the early 1900s. Yet Evolutionists are boldly making huge extrapolations back over 4.5 billion years and more. There is some evidence that the rate of radioactive decay can change. If the decay rates have ever been higher in the past, then relatively young rocks would wrongly 'date' as being old rocks.
I've raised this point a couple of times in the past, but they don't seem to want to hear of it. I did get them to agree that the sun had to show at least 30 million years of age appearance if it was created suddenly a few thousand years ago though, as it would have to at least be beyond it's protostar stage to function as a sun. Granted, that's a lot less than the 4.5 billion years they think it is, but it does establish that a lot of other stuff, if created, might show appearance of age, including the planet, the moon, rocks, gems and other stuff that God would've included in his creation.
