I've spent quite a few hours on the internet over the years looking into this kind of thing, and there really is a plethora of 'evidence' if you know how/where to look.
Have any of you ever seen a UFO? Something else? Something you couldn't explain?
Here is a story from when I was roughly 8~10 and I think sparked my interest in this subject.
So basically my family and I were camping, roasting things over a fire, it was my family and I (mother, step father, sister, aunt and uncle and 2 cousins). It was about 11PM at night and as we were all sitting by the fire chatting, eating etc, one of my cousins notices something bright in the sky and tells the adults, they tell her to be quiet and it's just a star, so we just go about our thing with no one really paying attention. I'd say about 15 minutes later one of the adults looks up and sees the same thing (it was a triangle with bright yellow/white lights) and says something along the lines of "holy shit is that thing coming down?". We all look up and my cousin says "See thats what I was talking about before, do you believe me now?". And sure enough this triangle thing is slowly descending directly over us, I can't really estimate how high up it was at this point, but over the next few minutes it came down to just over the treetops and it was big. My parents were at a loss, so were my aunt and uncle, they were thoroughly freaked out at this point, as this thing was just there... hovering, motionless, with it's bright lights. So as we sat and watched it for a few minutes, it suddenly makes this weird noise, I cannot describe it at all, it was just very unpleseant, seemed to penetrate your head. At this point my parents started to pack our shit up as did my aunt and uncle, they didn't know what the fuck was happening and I was scared. So we pack our shit and leave the camping ground as this this was just staying there emitting this weird fucking sound. So we packed up and left and to this day my parents refuse to talk about it, no one has really mentioned it aside from me once and they told me to drop it, so it's kind of a taboo subject to talk about, kinda weird right?
Anyway, just wanted to share that with you guys, sorry if it's not very well written, but ya'll get the point I'm sure.
EDIT: I forgot to embed this youtube video, which is probably one of the best amateur videos I've ever seen of a UFO:
