It’s easier to blame the “global warming” god of the gaps than to do the hard work of investigating the real causes of these fires.
If the videos showed it in real time, not compressed, it wouldn’t look anywhere near as “simultaneous.”
One big weatherfront with lightning will start fires over a broad area as it passes, fires which would appear simultaneous in a video edited for time.
