That's an eye opener...
Seriously, the article and your comment hit on the most significant point. We see what we are conditioned to see by our culture.
Apparently biased misleading unresearched article- There are several archival reports of Revolutionary War soldiers seeing bright UFO`s in 1776 flying over battle areas... I researched this for 10 years and found a lot of reports in newspapers, archived journals, diaries in Canada/USA and Native Americans` accounts via oral histories by the talkers, etc., about fast and slow flying stars, lights, etc. and in the colonies, back to 1600`s. These writer guys are very lazy, never do their homework.
