Of course, Jose not only started talking about mysterious creatures in the sky, but some giant ones in space.

There could be all kinds of non carbon based life forms drifting around in space.
http://memory-alpha.wikia.com/wiki/Space_amoeba Perhaps a sci-fi TV series was hinting of such a possibility.

So many kinds of life forms might have evolved or been engineered to live off planet and thrive in space.

While some could be of a benign nature, others could be quite malevolent.

Such BIG & small space creatures could thrive without being in an atmosphere and might feed off the energy released from stars.

Some smaller ones could live in the sky & the threshold of space.

Some of them appear to be like sky-snakes or flying eels. Perhaps they started off in the water and eventually ones that could fly had evolved.

Some of these creatures might originate from prehistoric times when the atmosphere was much more dense. https://www.youtube.com/watch?v=cAYpwiOnJrA

Long ago, there might have been something like a cross between a Quetzalcoatlus & a Moray_eel. They might not even be from this world.

Smaller & lighter ones could still exist today, but that would certainly scare the crap out of people. Thus, every effort would be made to get most people to ignore the possibly of such creatures.

While its good to be skeptical, that doesn't mean that you you can't still be curious.

MonsterQuest provided some dismissive entertainment so that people could just laugh it off as bugs & dust. http://monsterquest.wikia.com/wiki/Rod ,

http://www.dresan.com/blog/?p=1932 One type of EBE wants to nest in your stomach or intestines.

Another type of EBE can absorb and clone you and all your shit.
