Why does lightning strike people? Is it accidental or inevitable that lightning in the sky meets things on the ground? How to produce it?

Lightning is a discharge phenomenon between clouds and between clouds and the ground. Not only people, but also airplanes, buildings, animals, trees and so on. As long as it is in this discharge circuit, it can be hit. This is what we often call lightning strike.

Lightning strike is accidental for some places and objects; However, if the position of the object is relatively high and the surroundings are prominent, it will inevitably be struck by lightning.

The reason for this is as stated at the beginning.

In addition, I would like to put forward a point that the role of lightning rod is limited, because the real cause of lightning strike is not friction electrification (although many experts also say so), but the cutting of geomagnetic field by convective weather system (I am the only one in the world who believes this at present), so lightning strike may occur anywhere, including ground buildings near lightning rod, but it is less likely.
