The Jack and The Beanstalk story ....

 

 

Stories like this was given out to humanity as childrens'
stories (to inculcate from an impressionable age) to stop

them from wanting to know about the heavenly realms
- climbing into the heavens - by putting fear into them ...
about giants and harm etc.

A similar biblical story is about man building the 

Tower of Babel to reach God or the Godly realms aka
spaceships, cities in the sky etc. God changed the"tongues"
of men - spoken language. Unable to communicate man
had to abandon the building of the tower. 

Climbing into the heavens is about knowing more

about the Truth behind the veil, truth about gods aka

aliens of high intelligences.

Another story is about forbidding Adam and Eve to eat
the apple from the tree of knowledge and punishing them
for doing so "for they have become like us"- ever an alien
creator god's fear of being usurped by man.
