The word water in New Testament instead means hydrogen.

I recall that chemical formula of water is H2O that is every molecule of water consists of two atoms of hydrogen and an atom of oxygen.

In everyday life hydrogen most often is not met without water (not counting dry tree and some other cases, and not counting modern technology things). So water is also a correct translation of the Greek word which in New Testament denotes hydrogen.

But the following quote from New Testament is about heavens, and here water is not a good translation, hydrogen would be better translation.

(2Pet. 3)
3 knowing this first, that in the last days mockers will come, walking after their own lusts,
4 and saying, Where is the promise of his coming? For, from the day that the fathers fell asleep, all things continue as they were from the beginning of the creation.
5 For this they willfully forget, that there were heavens from of old, and an earth formed out of water and amid water, by the word of God;
6 by which means the world that then was, being overflowed with water, perished.
7 But the heavens that now are, and the earth, by the same word have been stored up for fire, being reserved against the day of judgment and destruction of ungodly men.

10 But the day of the Lord will come as a thief in the night; in which the heavens will pass away with a great noise, and the elements will be dissolved with fervent heat, and the earth and the works that are in it will be burned up.

12 looking for and earnestly desiring the coming of the day of God, by reason of which the heavens being on fire will be dissolved, and the elements will melt with fervent heat?

13 But, according to his promise, we look for new heavens and a new earth, in which dwells righteousness.

If we substitute water with hydrogen in the above quote then we see that this is exactly what science teaches:

At the beginning of the meta-galaxy celestial bodies (including Earth) were formed of hydrogen and amid hydrogen.

Galaxies perish (e.g. as a result of crash of two galaxies) being overflowed with hot hydrogen plasma (fire) which destroys celestial bodies with fervent heat. (Hot plasma is a result of the black hole in the center of a galaxy eating the matter of the galaxy, producing very much energy. This is similar to so called quasar, a hot plasma proto-galaxy from which a galaxy is born, accordingly modern science.)

(2Pet. 3:13) But, according to his promise, we look for new heavens and a new earth, in which dwells righteousness.gly science, after crash of two galaxies after much time passes, a new galaxy (new heavens), with stars and planets (new earth), is made of two crashed galaxies.

So having substituted water with hydrogen we have here almost exact match of Bible and modern science, what proves that both a true on this subject.

Well, how about Bible telling that God has created the Earth and heavens in 7 days instead of milliards years required for the processes with galaxies? I’m not a specialist in this field but I may suppose that in the past the Earth (or proto-Earth) was rotating very slowly and 7 days probably may be milliards of years, see also this my Web page. So there may be no contradiction regarding this.
