or less, under the form of burnt wood and volcano rocks that they
burn, they did not produce the SO2 (acid) that we have today.

All "burning" is oxidisation.

Burn sulphur and you get sulphur dioxide (SO2), add to water and you get
sulphuric acid (H2SO4). This was still true 4000 years ago.

Alas poor Fred, for he is gone.
His face we'll see no more.
For what he thought was H2O
Was H2SO4.
