In fact I do believe in them, I saw 4 UFO's once, 2 years ago and they were quite scary. Just a note before I continue, I also agree that they don't have to have a alien origin, don't be so SF occupied dammit
It was ~2 years ago and we logged fire with my friends at my village in the near river (it was very close by the village, around 5 mins far from the only shop in it) and we ate baked corn (is this the name of corn heaten on an outside fire? I'm not sure ) and told jokes, you know how it goes.?
Suddenly, I heard an airplane noise but it was too loud and we of course looked on the sky and saw a triangle shaped (like this -?/_\ ) plane with green lights on the bottom and which flew pretty lower than usual planes and after one of them passed from the south to the east behind the mountains, 1 minute there was nothing, and again one same 'plane' and 2 more correspondingly after 1 min.
When we went to the village to see if anyone else saw the event, only 2 people called that saw planes that were unusal and the other older people just heard the 'regular' plane noise because it was kinda cold and they were inside the shop playing ?cards
Nobody spoke of them the next morning and they were forgotten...
That's all I have to say about it, if you believe me or don't - it's?your?choice and I don't force you to believe in this. Look, the universe is huge, I am 100000% sure that we are?NOT?alone because it's?too huge for us only to be on our own. I think we had visits from outer space, but they were pretty rare and lower than 1% of the UFO cases were real, and from those we know maybe a few? I didn't believe in UFOs (warn: UFOs not aliens) before I saw them either, so just wait your chance to see one and you'll se that I was right
