What is the main idea of the following paragraph (in my own words)?

I would make just a few changes. I do understand what you want to convey with this paragraph. You have done well with your translation.

“Paraphrasing” is saying something someone else has said in your own words. You still express the same ideas, just in a different way. It can be a useful skill to have, especially if you are trying to write an essay or article.

Hope this helped!

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
