There’s supposed to be sparks when you connect the jumper cables to the chassis ground, right?

Sparks = “load present”. Whether “load” means ha ha very dead battery or something more dire, it depends.

If it bothers you, you can put them out with a little gasoline.

Probably already said by now. No not really but it’s a sign there’s a good connection and as long as nothing catches fire you’re good.
Assuming you only got them when you hooked it up. It’s normal for how many amps are behind that battery for it to jump the gap. If the sparks persist after the connection is made, it generally means the cable isn’t very secure. You should probably make sure it’s not going to hop off and touch something you don’t want so much power going through. Also it’ll get hot pretty quickly if you don’t address it and you don’t want that.

But there shouldn’t be current flowing through the ground unless something is wrong, right?

I think it’s normal? Isn’t that why you connect to the chassis instead of the battery? So that if it sparks, you don’t risk igniting any offgas from the battery?

You said you hooked up jumper cables. I assumed that meant booster cables for a jump start.
If you’ve got one end of a cable attached to a 12V supply which is attached to the positive battery terminal, and attach it to the chassis which happens to be connected to the negative battery, you have completed a circuit. Sparks will fly when the gap is small enough for the current to jump.
In the case of a jump start, you attach your positive terminals together and the negative terminals together, effectively putting the two batteries in parallel. You’re still completing a circuit (otherwise the jump start would do nothing) and sparks will fly when the gap is small enough to be jumped. You won’t get sparks when the first three cable ends go on because the circuit is open until you put on the last one.
The sparks are actually occurring because the heat of the arc in the presence of oxygen is causing the surface of the connection to combust, or so I’ve been led to believe, effectively welding with no shielding gas. You want to avoid it because it erodes the connection point. But it’s completely normal to get sparks.

Depends if that’s the one you put on first or second...
