What makes people follow a 10 years old kid talking about god and creation?

I think that the believer people are accustomed to see oldre preachers, because when they go to church, they listeb to a man talk about gos; but as we see in the video the child preacher, is a child who speaks about god.
Velievers follow the ideas of that child for that reason, because it is a child, and they are impressed by ''everything he knows'', they believe that is god's chosen, and says something very illogical. this child talks whith terms that a child of that age still do not know, an also talk with jokes, and in contradiction to the science.
For that reason makes people have fun of scientists ans see a child who makes fun of the scientists, and this makes people think tha science is wrong, this boy criticizes to the scentists because they say that god doesn't exist, and that people believe in god, that't why people applauded; but that boy is not even aware of what he says
