Best answer to child asking "Where does the rational number line start?"

What is the best answer to the simple question:
"Where does the rational number line start?"
Yes it goes on forever in both directions and we can all agree on that. Yet does that mean a line that goes forever in two directions does not have any starting point?
For ontopic discussion purposes, I'm talking about a single rational number line and not about the real continuous line or complex number plane.
So where does the rational number line start?
Or do we tell a child it doesn't start anywhere because it doesn't end anywhere?
