The event may still baffle scientists to this day, but that hasn’t always been the case. My source for the following is a book called The New Soviet Psychic Discoveries, by: Henry Gris and William Dick, p267, p263, p238–239.

In the opinion of Alexey Zolotov, who investigated the incident, when he was Department Head at the All-Union Institute of Geophysical Prospecting Methods: “This was not a meteorite or any other type of natural phenomenon. It made no crater in the ground. This was a compact nuclear device, sent with great precision, deliberately exploded over a relatively uninhabited area to let us know we are not alone in space”.

“I believe that it was a nuclear armed probe deliberately set to detonate just above the surface of Earth to attract our attention”.

You may find that hard to believe, or may not want to, but it was also the opinion of Dr. Felix Zigel, (at the time) Russia’s foremost authority on UFOs.

Earlier in the book it had been stated that eyewitnesses said that “shortly before the explosion, the Tunguska Body carried out a certain flight manoeuvre within the earth’s atmosphere, in the shape of a zigzag 800 kilometres in length… The sum total of all the evidence leads to the conclusion that the body was a probe from outer space that blew up within the Earth’s atmosphere for still not quite determined reasons”.

This account may or may not be correct, but I’m surprised that you found no time in your article to mention such a hypothesis.

Nowadays governments tend to suppress all information related to UFOs, so it’s not surprising that people are still talking about meteorites and other natural phenomena.
