Resonance is one of many things that goes into receiving signals,

resonance), amplify the heck out of it and extract the information
from the result.

What's that got to do with a current flowing to ground?

Ohm's Law. When you put a voltage across an impedance, current flows.
The voltage induced in a typical antenna is with respect to ground.
