The question of why alien races don’t visit Earth openly has sparked countless debates and theories. One idea is that advanced extraterrestrial civilizations may follow a "Prime Directive" similar to what’s depicted in science fiction, choosing not to interfere with developing civilizations like ours. They could be observing us from afar, allowing humanity to evolve naturally without direct contact, which could disrupt our social, political, or technological development. Another theory is that alien races might consider Earth too primitive or unstable for open communication. Given our history of conflict and environmental issues, they may see us as not yet ready to participate in a larger, interstellar community. Some suggest that aliens have already visited Earth but do so in secret to avoid causing mass panic or to study humanity discreetly. There’s also the possibility that their technology or biology operates on such different levels that we simply aren’t aware of their presence. Ultimately, the mystery of why alien races don’t visit openly remains unsolved, fueling speculation and fascination with the unknown.

It sounds logical that if you want something, you have to believe in it in the first place. It is like hypnosis and auto-suggestion, the more you repeat or think about and idea or concept and the more it will become a self-fulfilling prophecy

Because you can not censor the truth
