Well Hampus while evolution is a model, the notion that Aliens have visited/not visited the earth is not because it is a true or false statement.
So is evolution. It´s either true or it´s false. There´s no grey zone with evolution.
Either things evolved or they did not.
Let's say it like this, what do you want from this? For us to acknowledge that aliens have visited the earth as a fact or that the government has been lying about them since long time?
The first thing would be to start using some of that critical thinking in the other direction as well.
Seems it only works in one direction for some people.
Take Roswell. Military say themselves a saucer had crashed. Not an object, not a meteorite but a saucer.
The next day they change the story.
Here´s where critical thinking that you all hold so dearly goes right out the window.
You just accept the "new" story and get on with it.
"Nothing weird changing story just like that, nothing to see here move along"
Then when you see witness reports from people either being there or from their kids telling the stories they heard from their parents who were there saying they have been ridiculed.
Same with Phoenix lights. A whole city reports the sighting of an immense craft, so big you can land several B-2 Bombers on it.
The military again assumes the population is so ignorant and so retarded that they can simply state it was flares over a mountain.
Even the Governor saw it, he first went public with that then when the press conference came they ridiculed the whole subject by bringing in a man with an alien suite and him joking saying it was nothing weird that day.
Then 10 years later he apologized for ridiculing the whole thing and said he still don´t know what that was he say that day.
Population just forgets as usual and things go back to "normal".
It´s so obvious there´s a cover-up from the US point of view. You have the mexican military openly speaking about their UFO encounters.
When was the last time you heard anyone from the US military talking about UFO´s that´s still working there?
You don´t, the only guys you hear are former military personnel (over 500 of them) but again, just brushed aside when there´s very clearly something that is a bit odd here.
There´s a huge elephant in the room and most people are trying desperately to ignore it.
I can´t ignore it.
