First of all, because people are conductors, especially when they get wet.
During a thunderstorm, the clouds carry a large number of charges, and when the charged cloud blocks are close to the ground, the charges on the ground will be concentrated at the top of the higher object (induced charge caused by the attraction of different charges to each other), and when the charges gather to a certain number, they will break through the air and discharge, so lightning strikes occur. If a person stands on a high ground during a thunderstorm (especially above other objects around him), the electrical charges on the ground will accumulate above the person's head, resulting in lightning accidents.
In addition, lightning can also be transmitted indoors through wires and hurt people, so do not use electrical equipment during thunderstorms.

In thunderstorms, there will be thunderstorm clouds floating in the sky, the middle and lower layers of this cloud are mainly negatively charged, and at the tip of the ground protrusion, the density of positive charge will be relatively high, this kind of place is prone to lightning, if someone stays in an open place at this time, his body will act as the tip of this charge-dense, and it is easy to be hit by lightning!

Man is a conductor of electricity.
Thunder and lightning is a majestic and somewhat intimidating electrical discharge phenomenon accompanied by lightning and thunder. The condition for the generation of thunder and lightning is that there is accumulation in the thunderstorm cloud and polarity is formed. According to different topographic and meteorological conditions, lightning can generally be divided into three categories: hot lightning, frontal lightning (hot front lightning and cold front lightning), and terrain lightning.
Water vapor in the atmosphere is an internal cause of the formation of thunderclouds; The formation of thunderclouds is also related to the topography of nature as well as meteorological conditions. Thermal lightning is a type of thunder that often occurs in the afternoon in summer, often accompanied by heavy rain or hail. Thermal lightning forms quickly and does not last long, 1 2 hours; The length of the minefield does not exceed 200,300 km, and the width does not exceed a few tens of km.
There are about 1,800 lightning strikes going on around the world at any given moment. They emit about 600 lightning bolts per second, 100 of which hit the Earth.
Kampala, the capital of Uganda, and Java, Indonesia, are the most vulnerable to lightning. According to statistics, there are 300 days of lightning on the island of Java in one year. The most violent lightning in history was the 1975 attack on a hut near um Tari in rural Zimbabwe, killing 21 people.

When the two clouds meet together, it will occur like a short circuit in household electricity, because the cloud has a large amount of electric ions, so the electric spark produced is also immeasurable, when there is a conductor directly below, it will pass through the conductor to the earth, so there will be a phenomenon of splitting people and splitting trees.

This is a strong electrical discharge phenomenon, just like an ignition screen, which transmits electricity to nearby objects, but in fact, air can also conduct electricity...
