ufos and renaissance art

so i saw a nasa video showing the space shuttle releasing a probe with a large tether.  i find it strange no one really talks about the strange behavior of the "debris flying with us".  wtf is that stuff moving around out there?  looks crazy.  bizarre.  organic.  hmmm.  here's the video.

a couple days later i happened to think about some of the "ufos" in renaissance art.  strangely enough a lot of them appear to have the same organic structure.  like a jellyfish or or some single celled organism.  take a look at these examples.


                               

strange. a lot of imagery relating to jc. another item of notice is how some people in the artwork seem to notice these things in the sky while others are completely oblivious.  these are just a few examples i pulled from the web.  there are many more.  including cave art and other rock inscriptions around the world.

i don't know what to think.  
but it certainly makes me think.
