You either have left an accessory on or you have a short.

OR; (depending how big the big sparks are) it could be normal; as all of the capacitors and memories of all the different modules come back on line?
Get an ammeter connected between the cable end and battery terminal and let us know what the initial and then the continuous draw is.
Disregard this if there’s smoke along with the sparks. LOL

it sparks like you hooked jumper cables to the battery and took the other ends and touched the hot to the ground.

Well that is way too much to call normal; I would begin this by looking at the electrical items that can draw this kind of current flow first. Maybe try disconnecting the starter motor’s main cable; the starter’s solenoid may be shorted to ground?
At the main (large) starter terminal; you’ll see 4 or 5 smaller wire attached with the large battery cable. Those are fusible links; they are the main fuses that supply fuse panels, relays and other high demand components such as the alternator for one. Try disconnecting and then reconnecting the links one at a time; that may narrow down what circuit is at fault?
If you find one that when its disconnected the sparks stop; tell us what colour the fuse link is and what colour the wire it is protecting and we may be able to tell you what circuit it belongs too?

Without being there; I’m not sure what else to tell you? Other then keep looking, disconnecting and checking for bare power wires touching metal?
Maybe someone else here might jump in with some suggestions.

Dan has some good advise like he said it's hard not being there. Just one other suggestion I can offer would be to hook up a test light in series with the neg cable (one end on the cable & the other touching the neg term) it should light up. You can go over to your fuse box & start pulling fuses one at a time. If the light goes out or gets dim that would be the circuit with a short. Now the best way would be to use an amp probe due the fact this way may "wake up" the BCM but if even then you should notice a difference in the brightness of the light if you disconnect the circuit that has the short.........Just make sure the doors are shut & the key off when doing this.
