This would’ve been around 2010-ish. I could maybe buy that it was a stealthy military drone, although I kind of doubt any drone is that big or stealthy. But then, why would a military drone be interested in some random young adults hanging out in the park? I considered that it might’ve been testing the limits of its stealthiness. But then why did it hang around after we started talking about it, pointing at it, and trying to record it? No, it felt a lot more like we were being studied. Especially in the way it followed us. Slowly, smoothly, and with a little distance.

Definitely crazy any way you look at it; something was observing you, whether man or otherwise.

I personally could buy the "autonomous alien probe sent 10,000 years ago" narrative, but just seems like we'd have more concrete, widely distributed evidence by now.
