So, let's imagine the so called good ETs manage to free Earth. What will happen then?
Will the good ETs govern Earth? Will we be free to leave Earth? Will we be free to stay? What about the different religions? What about the humans who will fight the good ETs no matter what? Is there a plan for the time after the plan?
And what about the Saurians – the people Lacerta belongs to – assuming they exist? They are reptilians, but they are also indigenous to Earth and need the sunlight for their biology. Will they be free to return to the surface? I mean, as far as I'm concerned, they have the right to live under the sun. Will there be a peace treaty?
Giving us "You will see UFOs fighting in the sky" is by far not enough.
