I'm not sure what you are disagreeing with the Flying Dutchman about.
I gather from his his answer.He is not denying the existence of God rather as man,(We). Advanced through the centuries .He,(Us); learned that thunder is vibration set out as waves like a pebble tossed in the pond,(the pebble being the lightening.).Which we hear as sound we call Thunder. and the lightening we see as the bolt.we see the light first. Because it travels faster then sound.
The act is simply static build up between the positive earth let's say and the negative ions in the atmosphere.
That action,(rubbing of the two ion's),is followed by an reaction,(lightening,Thunder).Not gods'.However A god maybe the author of the physics.A sort of librarian of the Data base as described in my earlier comment.
