Old post!

not even 2% of an atom is solid matter. The rest is vacume. This makes the possibilities endless. If conscious energy believes and knows that ET life exsists then you will see it. Doesnt mean it came from space or ocean or deep past.
Convince the world they exsist and are hostile through the subconsciouse, ( Independance day, battlefield LA, ect.) suppress all technologies for 40 years but entertainment technology to keep everyone looking away.
Stage an alien invasion in front of the world with that supprest technology and offer a world militerized government to the people to keep them safe. The people in a panic will accept.
Totaliterian hell on earth and servitude to all matter will me the futur after that.
The possibilities are endless. Reality is only what the mind sees it to be.
