A smart brainless invasion
I would start by infiltrating those reality TV shows. That way I could easily brainwash people to worship me, do like me, want to be like me, giving their lives for me...
Then I will just call my peers to join Earth and nobody will argue.
Note to self: get rid of the earthlings competition first.
Earth Invasion Plan
First, I would attack and secure the major agricultural resources of the earth. Priority would be given to the highest yield areas that are far from large populations.
Second, I would leak photos of our alien species at these farms on the internet, especially on dubious crowd-sourced sites. The photographic evidence will convince the masses that any rumors of an invasion are a hoax. How? Humans, always confident in their own opinions, cling to their preconceived ideas even tighter in the face of evidence. The photos will surely be dismissed as doctored by pranksters and perpetuated by conspiracy theorists.
When individuals come to investigate, they will see armed guards dressed in uniforms bearing the Monsanto insignia. Unable to get close to the operation, they will return home to spread the news that the evil geneticists are trying to kill humanity yet again. We shall add to the internet speculation by suggesting that the corporation is covering up evidence of harm caused by GMOs, or that monoculture growing practices have enabled widespread pestilence. A bulk of the population will engage in bitter debate without even trying to discover the facts.
As food becomes scarcer due to our tight control of the farms, we will suggest malicious intent by any and all as the cause. No doubt it is Big Pharma that's to blame, since they are working on a medication replacement for food. Or certainly the Government is hoarding the food and denying its people in order to subjugate them. And it's highly likely that this is an act of terrorism.
The world will be in such a state of panic, backbiting, and hunger that they will welcome their savior: my people and me. "Save us, oh high and mighty alien beings! Teach us your ways of peace and harmony! Share your life-giving food, your cures for disease, and show us how to save our planet!"
Disillusioned, delirious from hunger, or deceived - all will come to me. And then Earth will be mine.
As an green man, it's been my dream to take over a planet. For years my species has been searching for other intelligent life. The thing about "inteligent" life is that we are really not the brightest in the bunch. Green history is taught to all of us green people. It's hard to look back on all the horrible things we have done; cannibalism, war, slavery of the Mingle peoples. Our people have also made huge advancemants; from space, to new solar systems, to solving our world problems. Green people have it all figured out. Since we have solved our problems, the government has declared a new goal for our evolution, helping others. That beind said, I am ecstatic that our top scientists have found not so intelligent life on Earth. These humans have huge potential! I am a Green man executive of exploration so it is my job to strategize and lead our infiltration. After months of studying, here is my plan.
The most rebelious group of the human race are teenagers - they have more flexible minds as well. They are at the prime age of changing their thought paths for logic. First we shall go into the schools disguised as teachers. We will teach them our ideas and nudge them to the right path. Surely, shaping a whole generation of humans will bring quick progess. Not only are teenagers flexible but they are passionate. After my studies, I have concluded that most humans lose their fire, after they pass through the teen phase. To get humanity's youth on board is to win the support of the entire race. Winning humanity's support means the success of our mission: evolving the humans to maximum potential.
