The distances are too great, and the number of possible sentient beings is too small. It hasn't happened we haven't been visited, and it likely never will.
If true, then in 1966, the USA already had flying vehicles which had no wings, made no sound, and could violate the laws of physics and make instant 90° turns with no banking or speed changes because I saw them with my own eyes. But you tell yourself what you want to hear.
