Does this mean all the comets we see/track, all of them originated in the Solar system? I would have imagined at least few comets would have originated outside our solar system.
It means that none of them individually are known to have originated outside, yes.
Long-period comets are thought to originate in the Oort cloud, short-period comets in the scattered disc or the Kuiper belt, and main-belt comets in the asteroid belt.
> They're supposed to originate in the Oort cloud.
AFAIK, our Oort cloud hasn't been observed, only hypothesized from the behavior of long-period comets.
Given that, it's kind of unsurprising we wouldn't have concrete evidence of extra-solar Oort clouds.
the same cigar shaped UFO has been seen since the 60s
I'm not saying this is a 100% UFO but there isn't a very good track record of NOT silencing people who worked and several individual witnesses that describe the same thing.
If the blue pill is comfortable (As it is for most people who believe the government can do no wrong, they won't lie, on the contrary we see them censoring and doing as well as they please) then fine.
Some of us have taken the red pill, and see what's really going on.
Not claiming that governments don't lie, but I think it's quite hard to see when they are lying, and some people just think that everything that comes out of "official sources" it's false.

That's not the government, that's scientists (although the OP does not provide a source for the claim, so...). Are they also lying?
