That’s right, MamaTexan.
You heard it.
Lightning.
And you know what lightning does to things, don’t you?
It depends on what you mean by 'things' and the power you are talking about. For the most part, I'm sure the answer you are looking for relates to "combustion" but remember that combustion is just a chemical reaction. If you are talking about a combustible material, then yes, combustion will occur, but lightening can also trigger chemicals to combine (throwing off or adding electrons into the mix, etc) or break apart.
Lightning occurs due to the existence of our particular 'atmosphere', and due to a change in potential between that atmosphere and the surface.
There is no evidence that there was lightning before there was 'life' and a conducive atmosphere on the planet. All evidence shows that the atmosphere has substantially changed over time, and that the prokaryotes and eukaryotes helped build this atmosphere.
