Pre-Sputnik Earth-Orbit Glints
IMHO, the strongest evidence so far that (some) UFOs are aliens just dropped.
This evidence is of many brief bright glints of sunlight reflecting off of big surfaces in high orbit around Earth, before humans had put anything up there, and correlated in time with both UFO reports and nuclear tests. Due to telescope imprecision and atmospheric fluctuations during photo exposure, each space source shows up on the plates as a circular blob about two arc-seconds wide. At GEO it would take an ideal ~22-35 cm diameter circle (perfectly flat, aligned, and reflective) to create a magnitude 15-16 image in these photos from a 0.04 sec glint.
