Time to run out and buy up people’s stuff who believe in this. Cheaply. But then, you’ll have to return it when they come back wanting it. Embarrassed no doubt.
Little too unrealistic.
Imagine people from Earth travelling to another planet galaxies away then not going out and explore it in public, but rather hide in our “spaceship garage” hidden under a mountain.
And wait for some of their people to wander to our location just before an apocalyptic event happens on their planet so we can save those few inhabitants.
