AsalamuAlaikum,
This is my humble effort to in order to help you with your problem brother. Any good in this post is from Allah and any errors or badness is from myself and shaytan.
Allah says in Surah al-Anbiya verse 30:
اولم ير الذين كفروا ان السماوات والارض كانتا رتقا ففتقناهما وجعلنا من الماء كل شئ حي افلايؤمنون
Transliteration:
Awa lam yara allatheena kafaroo anna alssamawati waal-arda kanata ratqan fafataqnahuma wajaAAalna mina alma-i kulla shay-in hayyin afala yu/minoona
Interpretation and Meaning:
Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? [Saheeh International]
Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And We have made from water every living thing. Will they not then believe? [Muhammad Al-Hilali & Muhsin Khan]
Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe? [Pickthall]
When the Quran says the 'heavens and the Earth' is it referring to the universe?
Allah in the Quran uses the Idiom Heaven and Earth to refer to the Universe as it refers to everything. Or he uses the term heaven to refer to the Universe.
How do we know Heaven and earth is an idiom for Universe. Well because all Allah ever talks about creating is the Heaven and the Earth.
And We did not create the heaven and earth and that between them in play. [Quran 21:16]
It is He who created for you all of that which is on the earth. Then He directed Himself to the heaven, [His being above all creation], and made them seven heavens, and He is Knowing of all things. [Quran 2:29]
Consider this following verse. We know that Allah knows everything in the Universe but does Allah use the Term universe or 'Heaven and Earth' in his Quran when describing it?
The Prophet said, "My Lord knows whatever is said throughout the
heaven and earth, and He is the Hearing, the Knowing." [Quran 21:4]
Our Lord, indeed You know what we conceal and what we declare, and nothing is hidden from Allah on the
earth or in the heaven. [Quran 14:38]
Also consider this verse:
Whatever is in the heavens and whatever is on the earth is exalting Allah , the Sovereign, the Pure, the Exalted in Might, the Wise. [Quran 62:1]
Just by reading through the Quran it is obvious that the term 'heaven and Earth' in the Quran clearly refers to everything - The Universe.

Have those who disbelieved not considered that the heavens and the earth were fused together, and We separated them and made from water every living thing? Then will they not believe? 'Rataka''s opposite is 'Fataka'.
This Ayah can be talking about the Big Bang theory.
Disbelievers couldn't have seen or thought about the Big Bang theory, or the fusion at that time; it was just an example. But today, these space explorations can brought to life. The origin of Universe can be watched and studied.One sad thing is that smart scientists who explore these are so fascinated by these explorations but their amazement is just with the universe. They can't seem to stretch their minds and think of the Creator who could have created these things.
So why did Allah not use the word Universe?Firstly was the word Universe even known in the 7th century?
But more importantly who are we to choose what words Allah uses in the Qur'an? Look at this verse why did Allah describe it as an old date stalk. Why didn't he just say it goes in stages etc.
And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. [Quran 38:39]
It is obvious it is for beauty. Allah uses a simile with nature. Similarly the constant repetition of the Heaven and Earth in the Qur'an also brings beauty to its verses.
But biggest point is Allah has used a idom for the 'Universe' he has split it into two sections. The Heaven (Stars, planets, galaxies etc) and the Earth.
"have the disbelievers not known"-this implies that they already knew this and not scientific miracle?No not really. The Disbelievers could simply just reply no.
But more importantly this verse is here saying to the Disbelievers don't you know everything was one solid mass. They didn't. A verse showing that Allah knows more than them and is above them.
Also brother Farhan_UDDIN view may stand as if you just read the context of the verse it clearly is speaking to the Jews and Christians
And We sent not before you any messenger except that We revealed to him that, "There is no deity except Me, so worship Me."
And they say, "The Most Merciful
has taken a son." Exalted is He! Rather, they are [but] honored servants.
They cannot precede Him in word, and they act by His command.
He knows what is [presently] before them and what will be after them, and they cannot intercede except on behalf of one whom He approves. And they, from fear of Him, are apprehensive.
And whoever of them should say, "Indeed, I am a god besides Him"- that one We would recompense with Hell. Thus do We recompense the wrongdoers.
Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? [Quran 21:26-30]
But i think the main reason why Allah uses 'have those who disbelieved not considered' is because the Quran wasn't meant only for the 7th century it was meant for all times.
So when someone in the 21st century- a disbeliever- reads "Have those who disbelieved not considered that the heavens and the earth were a joined entity". Allah is speaking to him and saying to him - you think your all scientific and know everything, look i'm telling you what you already know in a book from the 7th century.
I tell you when i give dawah and read this verse to people it is beautiful because it is speaking to disbelievers and Allah directly addresses them.
And Allah Knows Best.
