@alwaysstranger , i understand the fact that you really don't understand something but rather than having a way to express our own approach of views you kinda like tend to become arrogant and dissuasive, The Quran reveals things in manner that shows relevance,
‘When Allaah wills something, all He says to it is “Be!”, once, and it is.’”
And there are many other verses which speak of this matter and explain it.
Once this is established, then why did Allaah create the heavens and the earth in six days?
For example, Allaah says (interpretation of the meaning):
“Indeed, your Lord is Allaah, Who created the heavens and the earth in Six Days, and then He rose over (Istawa) the Throne (really in a manner that suits His Majesty)”
[al-A’raaf 7:54]
“Allaah mentions this period – i.e. six days – although if He had wanted to create it in an instant, He could have done so, because He is Able to say to it ‘Be!’ and is. But
He wanted to:
Teach His slaves kindness and deliberation in their affairs.
Manifest His power to the angels step by step.
And there is another reason: He wanted to create it in six days because
Allaah has decreed a course for everything, for which reason He He delays the punishment for the sinners, because everything has an appointed time with Him.”
