Not a chance. If any country on Earth had technology that allowed them to build vehicles that had instantaneous acceleration, able to go from 80,000 feet to the surface of the ocean in less than half a second (as observed by radar in the Nimitz incident) and stop instantly without any apparent G-forces, and that can operate equally well in space, the atmosphere, or underwater without causing sonic booms or any detectable disturbance while underwater, that nation would not just use it to show off unexpectedly every now and then. A nation that possessed such technology would be invincible and already in total control of the world.
However, I agree with others that I don’t think these are just aliens from other planets visiting us. I think the more likely explanation is interdimensional, as in fallen angels (demons). I don’t think we’re being visited from afar, but rather being observed by entities that have been here as long as Man has.
Read The Unseen Realm by Michael S. Heiser. The most interesting book I’ve read in years by a Biblical theologian. It’s an eye opener.
