Something I have understood over the years is that people are gullible or not, and regardless of their level of academic instruction. Just by looking at religions you can understand this, evangelicals, Jehovah's Witnesses, Catholics, Jesuits, Mormons, Christians, evangelical Christians and I am sure there are other branches, they are people who hate each other, they do not get along with each other, they criticize each other and in the end it is assumed that they all worship the same invisible being. My thought on this is that human beings have always needed to believe in something more than just what they can see. In ancient times, people believed in and worshipped the forces of nature, among other deities related to all kinds of things. At a certain point in history, they evidently sought to change that and centralize religion, and that was the point when people began to be controlled through religion, telling you what to do and say, how to dress, and above all who to worship or from whom to expect favors, favors that don't come unless you dedicate your life to paying homage to the imposed doctrine. And so, others then shaped the game in their own way and the rest of the derived religions emerged.

All of this leaves us in the present century, where even though information flows freely in some places, there are still others where that information is censored or modified at will to influence in one way or another. Many people choose to believe in other things, I for example choose to believe that religion and divine creation is a farce and that our origin is something more mysterious and that the information about the true origin of the planet and the first human civilizations was erased so that another story could be told. And in the end each person decides to believe in what seems best to them, some out of disbelief, others out of conviction, and others because the pieces fit together and they see the world from another perspective.
