The theory of relativity, on the other hand, is not so measurable - you'll just have to rely on faith unless you have a Millennium Falcon, since the stepping stone between theories and laws is tangibility... Which is why most science (especially theoretical science) is dependent on consensus - no different than religion (take a look at how the Talmud was assembled for reference.)

Actually the theory of relativity is very measurable. Your iPhone would not work without time dilation.
Here is a list of various tests for the theory of relativity:

And back to the topic of the discussion, the age of the earth is very measurable. Saying it is any younger than a couple of billion of years makes you look like an anti-science loon.
