We are either far more advanced in our space technology or there are non-human craft interacting with us. From where, who knows, I suspect we do already if it’s not our own craft.
My brother witnessed a UFO, my great uncle a cop in the 60’s saw a classic saucer hovering over a corner of the Wright-Pat base with his partner at 2:00am. Neither reported anything.
I suspect we are.....They certainly were able to keep the A-12 secret
