I think you'll find a lot of so called evidences from the middle part of last century to the 70's-80's looked like they do because of hoaxers who
do not actually research ufology, they create fakes according to their own intellects, which seem limited, as much as anything else.
There were loads of people trying to cash in using the ability of channelling, which most couldn't channel a sprite let alone a non Terran
intelligence, to create varying forms of extraterrestrial evangelism etc.
Bloody fruitcakes most of them, i've watched videos of these folks and i have channelled myself on occasion, (Don't ask, i don't divulge anything,
i keep it quiet and let the correct people know if i need to pass anything on.) so i am familiar with how myself and others are when they actually do
channel, beit it entity or advanced being but some of those jokers are absurdly laughable or would be if the damae they did to ufology back then
wasn't as serious as the numbnut hoaxers of today muddying waters.
But 50-30 years ago, people paid into that sort of thing.
If you watch something like Ancient Aliens, you'll see that throughout history there have been people recording Non Terran Craft in paintings etc and
those are similar to what we see today.
There is a relative physics reason why some craft 50 years ago may seem a more primitive configuration to those arriving in recent decades.
Which is simple really, faster and better ships leaving the same planet a lot later say 100-200 years apart for example, may lead to 50 years ago here
having first arrivals in more basic craft and a few decades later the faster craft travel the same distances in less relative time so arrive to us a
few decades later but departed their planet of origin a couple of hundred years later than the ones arriving here 50-60 odd years ago, time frames are
for example nothing else.
If ya catch me drift, loike. It's an explaination but methinx it may apply to maybe one maybe two of the common observed species, others have always
seemed to have advanced craft as we perceive them today in scifi as can be extrapolated from history if we look and also of course in decent non
hoaxed photgraphic evidences and pilot and other observer testiment.
But there are many species which visit this planet, have done since thousands of years ago and the advanced configurations can be discerned in some
very good artworks from hundreds of years ago and longer, also some of what is written into some cultural records from antiquity, aka mythologies,
describe things which are not exactly low tech' dustbin lids and string etc, the descriptives are of things very advanced indeed.
Ancient aliens is uploaded here by jimbobjoeboo as too a lot of very good ufological material mainly from the history Channel.
