I know the UFOs = aliens theories are fun to speculate about, but I find it kind of funny just how human-centric they have to be to exist.

Besides the unfathomable size and scale of space and time in the inhospitable voids of outer space, along with other reasons it's unlikely extra-solar intelligent life has visited Earth... they all require this perhaps even-more ridiculous notion:

We're actually worth visiting.

If I existed in some intelligent race capable of traveling near light-speed, making spacecraft impervious to impacts with fictional materials, traveling for centuries on end across the galaxy, and my intergalactic government council proposed using a monumental amount of resources to visit our dumb-asses just to buzz around and confuse military pilots, I'd be like "Hell no. Can we not do that?"
