When I disconnect the battery and reconnect I get a spark one time only then nothing. If I reconnect and turn on ignition, I then recharge whatever it is and will get a spark again with ignition off but only once, then nothing again until ignition is turned on again. I think it is slowly drawing the battery down also when connected.
In the days before electronics in vehicles, a spark when connecting a battery when everything is switched off would be significant and a positive indication something is drawing enough current to discharge the battery.
Since electronics arrived and things like central locking, a spark when connecting is normal and it is necessary to connect an ammeter in series with the battery lead to detect a steady discharge.

It sounds like a Body ground problem or a shorted Battery. Try using jumper cables and connect the NEG jumper cable to a body part on the Firewall. Then see if the lights and accessories work. You can leave the Battery cables in place. If the lights work, see if the car starts.
Dirty Battery cables can also cause this problem. So can a shorted Battery, though I would think a lightbulb would work with even a shorted Battery. Everytime you disconnect the Battery you are making a new connection when you reconnect the cables. The ends should be shiny not black.
You can eliminate the shorted Battery by disconnecting your Battery cables and use the jumper cables to bypass the Battery and use another vehicle to run yours via the jumper cables. They you will know if the Battery is shorted.
Autozone and Oreillys do free tests on Batteries and will scan your car for free if you can get it there.
