What might happen if we declare aliens existence?

So this article is based on my logical analysis of showing my own perspective. It is not meant to prove or disprove aliens existence. So starting back in the days, where people were relying on the government solely then time went by and they started to have freedom of choice law which changed how humen would perceive inputs. "The stare who scares" did you ever heard of that expression? It is real that humen in nature had been living in insecurity and fear from the unexpected events.and that goes in general for everyone one who denies it and who accepts it.but that also applies to us based on our life experience and how did we choose to live? I personally believe that humen in general are actors of their lives. And humen act in purpose either for protection from negative inputs outcomes who were surrounded by or because they can't find their answers correctly, or because of not finding their true personality that fits into their society liners.
So we sometimes act of a person who aren't us for various reasons and the main reason would be not to isolate ourselves from the society in general. So what if the unexpected happened away from humen favors? That would lead to one answer which is "reject it and defeat it" but why? Cause accepting the unexplained would trigger our intelligence levels, it would also isolate or separate our reality inputs that were implanted in our lives from others. So if aliens were to be real should or shouldn't declare their existence? I personally would say I support the break point where it takes three stages.first stage would be deny the aliens existence till they can speak to humen and straighten forward their motives of visitation, that gives any unexplained entity a good self impression about humen. Second stage would be determination if either their inputs would benefit humen or not .and the final stage would be work around them which means we might declare only the self determined aliens who are the same page with us and deny the rest. Since at the end when the question comes as "who to blame " then we got our answers which will verify and proof our benefits from the aliens and our loyalty of not hidden them from the public . So there is no "who to blame " besides if aliens screw around their promises of helping humen then "who to blame" will be the aliens deceiving strategy.besides that I support the idea of protecting our planet from any invaders.
Now if Aliens were to show humen their advanced technology and extreme power that exceeds humen capabilities then how should we deal with that?
We always have to remember our humen rules of fear and insecurity. It only happens when we face higher energy that exceeds us.thats why we get scared from a particular person or animal. So it is not by size it is by energy manipulation that scare us.what about the Aliens?if they exist as powerful more than us,what would scare them? The answer will be simple which is putting ourselves in their shoes so that would be first proving the aliens as stupid and powerless to each other in their territory and that's can be done simply by our intelligence thoughts. The aliens second fear would be the opposite of each thing they do . Think about it! You face a lion with no self defense. The lion wanted to attack  but you walk faraway from him and sit down and look at him .the lion might wanted to attack then will spend time of observing you then watch you calm then the lion would have to leave. Some might think he still have to attack because he is hungry? But I think he has to leave since your energy is more powerful than the lion as determination and result.the lion might still want to attack but he has to look for a different plan for you not as you sit far looking at him calm? That scares the lion.
Same as aliens. So we should as humen declare any powerful entity as powerful because it is the truth we can't deny and because we do not want to look insensere among our species. Think about it! If you realize a certain person is strong, others will realize that too,if you try to proof to others that you are stronger than him,others still see the strong person as the original and others will then focus on you to compare your strength to that original. And others will need out of ordinary results from you to cancel the original person image in their perspective. And while others are observing you .your main focus would be on what makes that person strong.others will see you as jealous or copy cat of an original. Then you will create strength methods that compete the original. Others would not see you as an icon they will see you as a debunker who has to have the original inputs first.you just declare the truth and that's what make you strong,then you enhance and empower your weakness by self only.
