Yes, you are right the Nasa seal was created or let's say published first. But it was created to inform mankind that in the new kingdom it would be us, the human race in peerage with other races and beings to explore the universe and gain our own experience. And they also show us new technology that comes with it, to prepare the people.
To the second part of your question, yes it is and was always teleological in nature. The purpose is to grow and gain experience. But what has to come? They show it to you in STAR Trek, STAR Wars, BattleSTAR Galactica and STAR Gate, which are all based on reality.
There is a reason that all of these were created with Jews running the operation.
Star Gate represents your present level of advancement.
Star Trek is humanity's immediate future.
Star Wars is a representation of the Anunnaki Empire, and a loose representation of some very ancient history.
And Battlestar Galactica is a sci-fi retelling of a lost tribe of Israel.
We hope that we could answer your questions and want to say "thank you" for your comment!
