Peace Lobotomise.
When the "night and day are mentioned it means also "Earth ". i.e the verse/s is/are talking about earth .
It is obviously emphasized in the verses that “night and day” also move in an orbit. The reference made to night and day in the Qoran is always related to the Earth’s night and day. In other words, what is actually stated in these verses is the fact that Earth also revolves in an orbit just like the sun and moon!
For a moment, think about the movement of the earth in the space. While the earth is revolving around the sun, night and day which always and together exist above the earth also revolve in an orbit around the sun. From this perspective, the verses have an extremely subtle expression.
GOD bless you.
Peace.
Peace, Good Logic.
The problem is: it is not just about this verse. Throughout the Quran, the alternation of night and day is
always associated with the sun and Moon's movement only. This means those verses are implying a geocentric model of the universe!
Now with respect to Quran 21:33, I don't see how it is speaking of the Earth's motion too? The alternation of the night and day has nothing to do with the Earth in Quran 21:33. The problem is you were presupposing the motion of night and day to mean the Earth is moving-and I do not see that connection. Quran 21:33 can be parapharased as saying:
Look at the night and the day along with the sun and moon, they are pursuing a rounded courseThe fact that the verse neglected to include the Earth in here is telling. Also the fact that the motion of the sun and moon are put next to the alternation night and the day implies that the author is painting a geocentric picture of the world. Is what I am saying here unreasonable because to me it sounds right?
