I'll Just Leave This Here.

  There are quite a large number of people who believe most of that. Some of them are actually highly intelligent, far above average. Some are not. Some can be far below average. Do you know how to tell the difference? The intelligent ones are capable of showing how they know such things, or how they came to whatever degree of certainty it is they have. Because they saw them on a fancy Youtube video is not how they know things. People of remarkably low intelligence believe things simply because they saw them on a fancy Youtube video.

   That particular video is like far too many things on the internet. It contains data, but it is in "raw" form. It does not build a case for the certainty of its conclusions, such as they might be. For the certainty of its conclusions it depends on the sort of things that people of remarkably low intelligence typically do. For example, "if this were not true could we make a fancy Youtube video?" Or, "this is what most people believe to be true, notice our click count."

   Real scientists do use audio and video equipment in their work, but the video you linked is not an example of that. It is specifically for people who learn things by rote for whatever reasons.

  The expression "by rote" is often used disparagingly. However there are quite many things it can be very efficient and serendipitous to learn by rote. People who do what they are told without questioning it can save themselves and others a lot of trouble, heartache and precious time. They don't need to repeat the mistakes made in the process of arriving at the truth. Constantly retesting things is not efficient. The details of the advancement of living things throughout time are rather voluminous and would take quite many semesters of college and already took quite expensive field work.

   So please note that I am not complaining about you learning by rote where that makes sense. There is a tiny problem with rote though. Sometimes people who do what they are told without questioning it get bad leaders. Whether they or the leaders are to blame can depend. Sometimes they themselves choose bad leaders. Sometimes unscrupulous leaders deliberately deceive them. Then mistakes get made again and the process needs to repeat its long way back to good order.

   A glaring argument your video deftly avoids is the "tornado in a junkyard" one. Many people claim that the junkyard scenario is not analogous to the way biological systems develop. Others actually believe that given enough billion years tornadoes will assemble working automobiles. Decades of research however have shown that there is a valid analogy, however loose, between the assembly of automobiles by tornadoes and the assembly of life by such natural agencies as could possibly exist given what remains today on Earth. And the likelihood of either is zero. Each assembly absolutely requires an agency that is not in the scenario. Your video failed to explain the origin of the prokaryote.

   At one time people who do what they are told without questioning it followed the rules from their religion like the Ten Commandments (on television tonight). Lately though many of them no longer recognize their religion as an authority. They have accepted godless authorities and mindlessly repeat things from them, for example your video.

   People who do what they are told without questioning it often believe they have sound reasons for what they do other than simply because they were told. It is interesting for example why they believe all men must wear their hair short like very little boys. On close inspection it is a rule they follow first and explain later, but not very well.
