UFO Attack of Dutch Harbour

Alien beings had visited Earth more often than realized, through the last numerous Centuries,. This depiction is circa 1640. Alien beings must be flying in & out of cosmic portals from another dimension, time & place. Their ongoing observation to study humans evolving seems like a logical reason they're here. Now us humans have noted strange occurrences, that seem to be Alien activity. However, we've not observed anything they've done for any long periods to understand their purpose. This scene must have had people react hysterical, with such a crazy sudden invasion. Nobody wanted to talk about their perceptions, or they could be persecuted as being disillusioned, insane & then be pointed out as being into sorcery. Just like women who were accused of witchcraft, those talking about weird flying discs or bizarre creatures were deemed guilty, & possibly were tortured with no trial.
