My two pillars of belief in non-human visitation: sample size and motivation

When I'm asked why I believe so strongly that Earth has been visited by non-human intelligence, I typically point to two main trains of thought:

1. sample size. This refers not only to the vast sample size of time and space capable of producing such an intelligence (which is a supposition), but mainly the sample size of credible and official witness and whistleblower testimony. I am not one to believe in one person's outlandish story, and I'm unlikely to believe a story from a group of people who I do not find credible. But man, I don't know how you shake Grusch and Nell and Elizondo and Fravor and Graves and all of the other similarly positioned and similarly sober accounts of what is happening. Just one of them, sure, could be crazy. Just two or three, could be disinfo. But the number is too large to brush aside. I don't need video proof or a dead alien or the president to make an announcement in order to believe these people. I believe them because they're believable. They fit my mental model of truth tellers.

2. motivation. This is for the part of the story where people try to explain every credible sighting and story as advanced human tech. And this is one where, for lack of a better explanation, you just have to know people. You have to have a really good grasp on what motivates, not just yourself, but the species. What drives them to do what they do, and when do they seize opportunities. And quite frankly, it's a bullshit story to think that secret human tech has been operating outside of the bounds of modern society for decades, all across the world, and nobody has once revealed it or made money off of it or won a war with it. The phenomenon isn't new, and it's not logical to suggest that it's ours. Government, private, you name it. It's not all human, and it certainly didn't originate from humans. You can't lap all of modern science in a private bunker. And if you did, you'd exploit it immediately to make the most personal gain possible. You think a government could tell you what to do if you controlled one of those things? You could rule the planet, you could do whatever you wanted! No, humans didn't invent the things we're seeing in the skies. They probably have been able to replicate some of it, but they sure as hell didn't invent it. Someone else did, and that's the only thing this whole planet should care about.

We are not alone.
