Were Fundamental Constants Different in the Past?
Atomic physics, nuclear physics, and cosmology enable physicists to probe changes in the fine-structure constant over time scales ranging from a few years to nearly the age of the universe.

Were Fundamental Constants Different in the Past?: Physics Today: Vol 57, No 10
The general point is that scientists would be extremely interested to know that physics was different only a few thousand years ago. But if it was, it would be very obvious and we would see the evidence everywhere.
One pretty catastrophic piece of evidence is that for the radiodating regimes to be wron radioactive decay rates had to speed up. As decay rates increase so does heat. It's estimated that to change decay rates to make it look like the earth was 6,000 years old, the temperature of the earth would then be 65,000C/km. Rock would be liquid.

We do not see any evidence that anything was different and we have evidence that it was the same. So that's game over - if it ever started.
So we must wait for the crackpots to produce the evidence that it was different. I'm not holding my breath. This current dad loony isn't going to produce anything, why are we still feeding him?
