This is your belief. in the enumeration given by Virgil

all rationals get their index here. Can you name any rational without an index?
No, therefore you prove nothing, you only claim that something which is vaild for all finite natural numbers MUST BE
TRUE also for something
infinite. This is not correct.

It shows only that a finite number of naturals is not enough to provide indices for all rationals. That's it!!

Don't be sad:

What is now with your proof that the reals are countable:

Why you don't say if it is right or wrong? I'm just curious.
