Is there like different realms of existence, where all but one are under another?

One in heaven, one under the heaven, one under the water, and one under the earth?

For those of us who are currently living on the earth, we are under the heaven / under the sun?

Ecclesiastes 2:3 I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what was that good for the sons of men, which they should do under the heaven all the days of their life.

Ecclesiastes 5:18 Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.

Is there also an existence under the waters?

Job 26:5 Dead things are formed from under the waters, and the inhabitants thereof.

Is there also an existence under the earth?

Proverbs 15:24 The way of life is above to the wise, that he may depart from hell beneath.

Isaiah 14:9 Hell from beneath is moved for thee to meet thee at thy coming: it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations.

Yet, are not all those existences under Jesus?

Revelation 5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.

John 3:31 He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all.

By his incarnation, ascension, and his soon to be, second advent, doesn't Jesus show how he has power over both realms?

Matthew 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.

By his resurrection, doesn't Jesus show how he has power over the realm beneath?

Revelation 1:18 I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.

Then by speaking to the storm, and walking on the water, doesn't Jesus show how he has power over the ream of the sea?

Matthew 8:26 And he saith unto them, Why are ye fearful, O ye of little faith? Then he arose, and rebuked the winds and the sea; and there was a great calm.

  27 But the men marvelled, saying, What manner of man is this, that even the winds and the sea obey him!

Matthew 14:25 And in the fourth watch of the night Jesus went unto them, walking on the sea.

Are there not clear boundaries, or borders, between the realms?

For instance, with the boundary of the sea, doesn't water have a distinct surface, like with a glass half full of water, where the water starts/stops is clearly visible?

Couldn't have Jesus created it differently, but he didn't?

It could have been, like, water, but above a little, like a fog mostly, but above that the fog increasingly has less water, until no fog, only air?

But, instead, why did he make it with a distinct layer between the two?

And wasn't that the layer that Jesus walked directly upon?

Also, going up from here, even though there is less and less oxygen the farther up we go, how come thre is not more and more heaven as we go up?

Instead, doesn't heaven open like a door?

Revelation 4:1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.

Revelation 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
