Creation

Seeking a few clarifications:
Who are the 'they' you are referring to?
Where do you find the concept of 'an edge to the sky'?
Not at all what the towers were for.

By "they" I mean early Christians and Jews.

And the word firmament is used during creation serveral times

The firmament is the sky, conceived as a solid dome by my logic that means it has an edge and an other side

Genesis Chapter 1 : 6: And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.

7: And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.

8: And God called the firmament Heaven. And the evening and the morning were the second day.

Thanks for the clarification.

Let's add verse 9: And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.

The word firmament literally refers to a great expanse and, in particular, the vault of the heavens above the earth. It denotes the literal sky that stretches from horizon to horizon. In verse 8 He calls the waters above Heaven and in verse 9 He gathers the waters below unto one place and names them the seas (vs 10). So in modern day language God creates the horizon (or Earth's atmosphere) and thus divides the heavens (outer space) from the earth. (Note: I can't give you an exact altitude for the firmament.)

In light of that, I'm not sure how to answer your initial questions. Suffice it to say, some astronauts have been to the edge of the fimament and beyond.
