Years ago I read the hynek ufo report/ book. Full of fuzzy photos, indeterminate videos, stories of abduction etc.
That was 60 or 70 years ago, technology has moved on. And yet we still get fuzzy indeterminate photo's and videos.
Something tells me it's a load of bollocks.
As someone who is really into the topic, I've resigned myself to the fact we'll never get definitive proof, and that's if it even exists.
First off, If there is alien species with capabilities of visiting earth, they certainly don't want us knowing about it or they would show themselves, wouldn't they?
So either they don't visit and it's all bollocks or they do but they don't want you to know and have some agreement with the powers that be not to just rock up in public.
Now let's say it's the latter, for the sake of conversation, then there's absolutely no chance you're getting full disclosure from any government or associated organisations. That'd me a massive can of worms opened as its just them admitting they can hide something so big from the public and did. So they're never going down that route
That's why nobody interested in this topic will ever get satisfactory solid proof. The government might feed you a few "top secret" grainy videos and even then you have to question why? It's not for your benefit, Its always for theirs.
So the reality is either its all bollocks, or you have alien species coming here that clearly have no desire to show themselves, or you have governments who are clearly able to keep what they know from you to the point even supposed whistle-blowers can't provide proof.
Whichever way you look at it, it means nobody will get 100% solid undeniable proof.
