No water needs to be added. When the flood happened, water had not compressed material below the water yet, that is why this amount of water was enough to cover everything. After the flood, water that weights a lot, has compressed material below it, which is why ocean floors have gone down, causing the illusion that mountains rise. And material below the water has been compressed means, air has escaped causing the material to be in more compact form.
By what the Bible tells, God wanted to have free individuals. And second plan is that He wants to give eternal life for those who become righteous. Others will have only limited time.
Why do you believe it is rising and not that the reference point is going down?
The flood myth is a reworking of Mesopotamian stories:
Flood Myths Older Than The Bible - Dr. Joshua Bowen
Assyriologist who specialized in Sumerian literary and liturgical compositions
1:25
OT scholars will say Genesis is using a Mesopotamian background and apologist will say
“Well no, there is no literary evidence that shows it borrowed, we cannot show literal evidence”…”it was in the air”….”how do you know it wasn’t true”…….somehow downplaying the Mesopotamian background…
2:57 Dr Josh Bowen - there is no question as far as Biblical scholars and Assyriologists are concerned that the Biblical text is much later than Mesopotamian text and it’s borrowing directly or subtly from Mesopotamia.

Enuma Elish, Babylonian creation myth Genesis 1 borrows from, is recited every year at the New Years festival. Exiled Israelite kings were in captivity in Babylonia. Genesis was written after the Exile.
Genesis demythicizes the Babylonian stories.

“(Well we don’t know which came first), is nonsense, we do know. The textual tradition for the flood story is much much earlier than the Biblical text. Israel is NOT EVEN A……”

Noah - And the ark rested in the seventh month, on the seventeenth day of the month, upon the mountains of Ararat.
Noah - And he sent forth a raven, which went forth to and fro, until the waters were dried up from off the earth. Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;
But the dove found no rest for the sole of her foot, and she returned unto him into the ark, for the waters were on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark. And he stayed yet other seven days; and again he sent forth the dove out of the ark;
And the dove came in to him in the evening; and, lo, in her mouth was an olive leaf pluckt off: so Noah knew that the waters were abated from off the earth. And he stayed yet other seven days; and sent forth the dove; which returned not again unto him any more.
Gilamesh - . When the seventh day dawned I loosed a dove and let her go. She flew away, but finding no resting- place she returned.

Noah - And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.
And the LORD smelled a sweet savour; and the LORD said in his heart,
I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth ; neither will I again smite any more every thing living, as I have done.

When the gods smelled the sweet savour, they gathered like flies over the sacrifice.
Noah - The earth also was corrupt before God, and the earth was filled with violence.
12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
Gimamesh - “Wisest of gods, hero Enlil, how could you so senselessly bring down the flood? Lay upon the sinner his sin, Lay upon the transgressor his transgression, Punish him a little when he breaks loose, Do not drive him too hard or he perishes; Would that a lion had ravaged mankind Rather than the flood, Would that a wolf had ravaged mankind Rather than the flood, Would that famine had wasted the world Rather than the flood, 26 Would that pestilence had wasted mankind Rather than the flood
