Creating a plant killing itself by "magically" making its nodes explode at some point is just nuts.
Creating a shtload of atomic bombs that together can vaporize our planet is nuts too, yet we did exactly that.
Just because it seems unlikely, doesn't mean there can't be a rational explanation for these events.
How do you come to such a conclusion? It's like saying that you're sure that your elbow-joint can explode...
Explosion just means there has been a radical reaction basically, why assume there's some kind of extraterrestrial magic involved? I really don't get that assumption, nor line of reasoning. It's the least likely explanation, let alone a realistic one.
