A Guide to doing Religion Wrong!

Just a question to this. How do we KNOW for certain that the rate of radioactive decay has always been the same?

Because it has been so in every observation we've made over every time period we could measure. The underlying quantum physics theory covering decay (which has been tested much more widely) also has no reason for it to change. The default hypothesis, based on all current observation until proven otherwise, should be that it's unchanging. What is your proposed mechanism for the decay rate to be different in the past? 

Scientists obviously haven't been around long enough to test or observe this. Its possible to have changes in these factors.

How?

Radiometric dating may be the best we got, but its not ultimately reliable because assumptions still have to be made in order to calculate a date.

Assumptions have to be made to suppose the sun will come up in the morning. Science, unlike religion, does not claim to be 100% correct.

Any test which entail even the slightest measure of assumptions cannot be taken at 100% certainty.

Correct. But you cannot avoid assumptions in anything. Maths. Physics. Philosophy. Video game sales. It only needs to be that those assumptions are reasonable.

Original number of unstable atoms in a rock cannot be known, only stable and unstable atoms that remain in the rock today.

Actually we DO know the original number. Because all of the atoms were once the unstable ones. So the sum of current stable + current unstable = original unstable. The only question is of rate.

Again its currently the best solution scientists use today but I dont see that it can be determined a fool proof measurement.

I agree.

The only people who claim certainty are the creationists.
