LET ME SUGGEST something with certainty.
"If and when" an advanced society of aliens from another planet becomes aware of human life on Earth, they will NOT send single spacecraft or small groups of spacecraft into our atmosphere to be sighted by humans on Earth.
Our introduction to others from interplanetary space will not be with a member of their society. They will communicate through their technological advancement, without the risk of having their members being harmed.
It would be wise for Naval Intelligence to work out a contingency plan for an interplanetary council meeting via hologram.
For this reason, human sightings of single or small groups of UFO-UAPs which have been reported beginning in 1947, are NOT of interplanetary spacecraft.
Any alien society which is aware of life on Earth will fill our planet's low orbital space with thousands of spacecraft for their first formal introduction.
Trust me on that...
