My following knowledge was acquired long time ago from a well known pastor and eschatology from a guy.
The 6 days of creation was often attacked by non believers, they said no facts and not scientific, indeed it was, due to most of our knowledge and theological explanations. So today, I'm going to clear up this vague.
First of all, just ignore all the theology explanations, and let us base on the bible words itself. In order to explain it correctly, we have to explain the words exactly, cannot add nor minus, cannot distorted, and also conform to science.
"Created" appear on verse 1, and "made" on fifth day, and "created" on sixth day of human creation, aside from these, first to fourth day, the bible didn't said it is created or made.
Next we observed, water is already existed before day 1, See verse 2:
"And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters."
Base on above, we can now say that God really created the universe, the earth, the sun and all of them, but it just the earth became without form... note the original text "earth was without form" can be translated to "earth became without form" It is not possible for God to create an earth without form, or darkness, and so God already created a beautiful earth before verse 1, how beautiful? there are dinosaurs and all sorts of prehistoric animals, plants etc... how long have it be been? wee don't know, but base on science, we do have some knowledge about those billions years ago's earth.
Now we think, who or how the beautiful world of prehistoric destroyed? Ans. Satan is already exist before verse 1, our world now is more or less 10 thousand years. It is a correct assumption that Satan destroyed prehistoric world.
So the assumption, when God use water to flood all over the earth, the surface of the water was covered heavily by clouds, and so the sun light cannot shine thru, note that only "darkness was upon the face of the deep." and other places were not, because outer space, sun and others were already exist, already created.
Then God said "let there be light, and there was light", this light is absolutely from the sun, because only the sun can let the earth having "night" and "day", and so every day of re-creation is ended in "And the evening was, and the morning was etc."
conclusion: verse 1's "in the beginning", in original text, is later than that John 1:1's "in the beginning" so this is the flow... John 1:1 literally said that the universe haven't existed yet, not even time, space and matter existed, and then Genesis 1:1, God created time, in the time container, then God created space (heaven) in it, then in the space-time container, God created matters (earth) in it. So actually verse 1 is God created the universe, including earth and also everything on earth, dinosaurs... they are just not written down, and even if write down all those creation in the bible, how can they understand those creatures? obviously not at ancient time, we know now that is because of science and technology.
to be continue...
