Solution
The best evidence of the reliability of isotopic dating would be that analyses using two radioactive isotopes yield the same age. This is because it shows consistency in the results, which is a key factor in determining the reliability of any scientific method. If two different isotopes give the same age, it means that the method is reliable as it gives consistent results.
