We're proposing that dynamical evolution of the universal constants (like e, h ,c etc) generated the accelrated decay. Decay is of course governed by these consants. It is already known that these 'constants' have not been constant.
You're talking about evidence that the fine structure constant may have been smaller billions of years ago by 0.00001%. The evidence comes from the light from ancient quasars. In other words, the reason they think the fine structure constant may have been different long ago is because of evidence. See

The light from stars only 5,000 years ago indicates that the fine structure constant was the same then as now to the extent we can measure. You have no evidence of any change whatsoever.
What's more, you need changes of hundreds of percent, not a hundred thousandth of a percent, and this much change would probably be visible to even the naked eye when peering at 5,000 year-old starlight. In other words, the evidence, if there was any, wouldn't be subtle and couldn't be missed.
