Some doubts

Walaikum Salaam Werty

Welcome to Islamicity. Wishing you a very happy stay.

Heavens and earth were created before the creation of man. Read this ayah :

"And when thy Lord said unto the angels: Lo! I am about to place a viceroy in the earth, they said: Wilt thou place therein one who will do harm therein and will shed blood, while we, we hymn Thy praise and sanctify Thee ? He said: Surely I know that which ye know not"

Note the words : Viceroy of earth {which clears us that earth was already created before man was created' If you remember there are other ayaat in Qur'an wherein Allah says as how He created skies and earth.

When Allah desired to create Adam He addressed the angels Allah said that He was going to create Man and appoint him as His representative on earth. As soon as the creation was accomplished and He had bestowed Adam with His spirit, He told them to bow down in obedience to Adam. The angels who considered themselves to be superior to Adam on account of their closeness to the Creator Himself, were surprised at this instruction to bow down in obedience to a creature that was molded from earth materials.

They said to Allah, "You are appointing a being as your vicegerent who would bring unrest and blood shed on earth, whereas we, who have been immersed in your worship were more deserving to receive this honor.

So all these explain us that earth was already created.

i think werty you have by mistake built your sentence wrong, i think you are asking that wether paradise is there or not right now in existence while we are on this earth.
paradise is already there in existence. but i think the verse you are quoting is not talking about paradise, the heaven over there indicates the universe. i would like to clear that in translations when you read "heaven", it does not mean paradise but it means the sky/universe.
when the sentence construction is "heavens and earth" it means the talk is going on about universe.
when the sentence is "earth and heavens" the talk is going on about atmosphere.
hopefully it will help you in your Quran study.
pls also go through my other posts in different sections if you are trying to understand Quranic concepts.
peace be on you
take care.
