What will happen if you miss up with aliens if they exist?

Aliens are basically extraterrestrial beings who lives off our planet earth. A lot of conspiracy theories had proven their existence in ancient times. Others debunk their existence by their scientific theories that they developed from unknowable sources. However,in this article I will base my overall opinion based on my common logic theory that I believe in .and you get to believe what to believe at the end. Starting from mankind or human they start from ancient times in our daily cycle that we have nowadays. Which is babies get born then grows as human. The question is,who taught mankind all technology and science and etc,since when we are born we get to learn? Ancient theory believes in Adam and eve and pyramids and cave men and so on.but the remaining question will be.if we teach generation after generation what was taught from ancient age then we will remain as ancient generations were without any advancement. Then you might think!the born of geniuses created the change to technology! But that leave us with a question.a genius would need tools and tools would be prepared by another geniuses. But in ancient time,they had technologies which was advanced that until now they can't achieve such as building pyramids. So how do we lack all knowledge of advancement all time nowadays. So the answer of geniuses create technology is not sufficient enough to get the correct answer. Some refers to natural disasters caused the lack of knowledge. But the question will be technology that we spend up in last years could not be existed without a reborn of a daily genius who does all that fast enough which is doubt to believe. Also all these historical sites that mentioned aliens aircrafts on their buildings wouldn't paint that or sculpt it for non sense.so look at how the universe work .it is all Aliens technology such as the body function,planets,gravity, etc
Now aliens were told not to exist in our planet but if aliens decided to come back I believe no thing would stop them.since based on what conspiracy theorists describe them as different entities who can live millions of years and go invisible to humen beside their abilities to control and monitor humen brain and their ability of telepathic communication to our unconsciousness. So basically Aliens can read your mind.so what will happen if we miss up with them? They might ignore us or start the war! So beside that they might play the revenge theory which will end us back in a cave! Since they are brain readers and control our mind they might be responsible for diseases.since they can go invisible they might be responsible for paranormal activities. Since they can create dimensions and transfer between them ,they might be responsible of people kidnapping unexplained. Since they can flip planets they can flip the earth to their favorite dimension of miserable situation for humen. Since they can go invisible they might be responsible for all things that people lose and can't find it. Since they can be inside people head you have no where to go basically. They will haunt you forever.
If Aliens could control energy then they might be responsible for climate change.
If Aliens can change their form since they can change energy and mass and consciousness then we might have aliens living as human forms on our planet.
If Aliens can control humen DNA then they can make their own alien human creature on our planet.
If Aliens are mind controlling human then they might be responsible for humen suicidal rate.
If Aliens can control humen consciousness then they might be responsible for humen insanity cases.
If Aliens are brain readers to human mind then once humen make a smart plan they can take humen to their planet .
If Aliens can read humen thoughts and memories then they know when you are outsmarting them by a sneaky plan then act nice.
If Aliens are brain readers to humen mind then they can hear all humen thoughts and talking and gossiping specially when they think to lower their voice.
If Aliens can read humen mind and thoughts and emotions then humen are telling Aliens where they are going and what they're doing on a daily basis for fun.
If Aliens can track human brain then they know all their gain.
Now if Aliens are not real then we got the jackpot! We just do what we want without any worries.
