Of life ,so we must prove following question :
1.water is an important composite of life (include any living creature),but the water is not only the important component part to form life, but also it is a vary important medium of the forming of life and life live.;
2.No water no living creature;
3.water first formed and after which the other organic of life formed on the earth;
4.what physical chemistry characteristic of water make prerequisites of generation and evolution of life.
1. water is an important composite of life:There are lots of research data which demonstrate
water is an important composite of life (include any living creature),the content of water in any living creature is more than 60%,in some water living organisms it is more than 90%,but the water is not only the important component part to form life, but also it is a vary important medium of the forming of life and life live.;
2.No water no living creature:when we are going to desert we would find there are water there are an oasis of life ,another example now scientist‘s only standard is that whether or not there is a water when he determine whether or not there is a living creature on some one celestial body .
Through above mentioned we see “water is headstream of life ”it is the truth in fact,but how to prove it on science ?“The fossils do not matter if the early earth's atmosphere was contributive or prohibitive to the formation of organic molecules”,for the past six years,we take a serial analysis for the origin of life on earth from quantum biology ,the result as following .
3.water first formed and after which the other organic of life formed on the earth;
27 kinds of elements are selected from those of 94 existed on the earth which make up organism and support life’s activity, see table 1.
Since these substance elements have been selected by life, they must have some physical and chemical characteristics which suit to constitute a life. From table 1, it can be known that of all the elements of the composition of organism, carbon(C), hydrogen(H),oxygen(O)and nitrogen(N)occupy more than 96%.On account of energy determine matter structure,so which formed first on the earth, water or life,s organic matter could be identified by analyzing the molecular structure mechanics of“H”,“O”,“C”,“N”in water and other life,s organic matter.
Table.1 constituent ratio of several main elements for life-form (percentage of dry weight)

C 50.00 49.80 43.57 55.99
H 8.00 12.40 6.24 7.46
O 20.00 6.70 44.43 14.62
N 15.00 31.10 1.46 9.33
P 3.00 _____ 0.20 3.11
S 1.00 _____ 0.17 0.78
The substance on the earth can be divided into three major kinds: inorganic , organic and water classically divided into inorganic(include water)and organic. Water standing out as one kind in our opinion is because its great importance for life’s formation and activity, What’s more, the atoms of water combine with each other via covalent bond, and this is the main link for atoms bounding of organic substance and various macrobiomolecules.
Great quantity of trial data shows the stability of covalent bond stands related to some bond parameters which includes the bond length, bond energy and the electro-negativities .
The bond length and bond energy of several mainly chemical elements of life are compared in table 2
Generally speaking, the stronger the electron cloud overlaps and the shorter the bond length is, the stronger the stability of the bond is.
If analyzing the stability of the mutual-compounded-elements of the three main sorts by the length of bond, it can be found that the bond length of ‘O-H’ is the shortest, ‘C-C’ the longest and ‘C-H’ the middle. By this token, it can come to a conclusion that the compound of hydrogen and
oxygen is the strongest among those of other elements.
According to the bond length from short to long we can obtain follow a progressive increase number sequence:
O-H(96.0)<N-H(103.8)<C-H(105.6) < H-S(135.0) <C-O(143.0)
< C-N(147.2) < C-C(154.1) < C-S(181.5)
Analyzing the stability of the mutual-compounded-elements via the bond energy, a decrease progressive number sequence can be as follows:
O-H(462.8)>C-H(413.0)>N-H(390.8)>C-O(357.0)>H-S(347.4)>
C-C(345.6)>C-N(304.6)>C-S(272.0)
table 2 :The comparison of bond length and bond energy of several mainly elements to life
Sorts of bond Length of bond (pm) Energy of bond (kj/mol)
C-H 105.6±1.5 413.0
C-O 143.0±1.0 357.7
C-C 154.1±3.0 345.6
C-N 147.2±0.5 304.6
C-S 181.5±1.0 272.0
O-H 96.0±5.0 462.8
N-H 103.8± 390.8
H-S 135.0± 347.4
In general, the higher the bond energy is, the firmer the compound between atoms is. From the number sequence above, it can be found that the energy of the compound of ‘O-H’ is highest, ‘C-C’ is lowest and ‘C-H’ is in the middle, thus it can indicate that the compound of hydrogen and oxygen is stronger than that of hydrogen and carbon.
Electro-negativities is a kind of ability that atom attracts bond electron into covalent bond. According to the average valence electron energy AVEE measured by photoelectron spectroscopy, we can see some statistics show the electro-negativity of the several main elements of life, see table 3
Table 3, the electro-negativity of several main elements of life
Elements symbols Electro-negativity
H 2.30
C 2.54
O 3.61
N 3.07
S 2.59
P 2.25
The electro-negativity of elements in life-form are arranged, we can obtain a number sequence as follows:
O (3.5) > N (3.0) > C = S(2.5) > H = P(2.2)
Therefore, it can be inferred that when the hydrogen meets with oxygen and carbon at the same time, hydrogen will combine with oxygen at first, because the electro-negativity of oxygen is bigger than that of carbon obviously.
Because of energy determine the combination of matter elements mutual and it’s order , for example, when we take a piece of iron into between tow magnet which different in size ,the iron will go to large magnet furthermore the large magnet can draw the iron which had attracted by the small magnet. Through the above analysis, it can be totally testified that the combination of hydrogen and oxygen had precedence over that of hydrogen and carbon on the earth whether from the point of bond length, bond energy, or from the point of electro negativity of elements. Therefore we believe that it is water that formed at first, and later the organic matter of life is formed.,in the remote antiquity period, a lot of material elements of life were colliding with each other, these atoms of elements were in an irregular heat movement because the earth and the space around it are undergoing a very high temperature. In the beginning, water formed in the space of earth is in form of vapor and when the temperature of earth and its space reduced to critical temperature(Tk=647.2k,Pk=217.7), water turns into liquid state,which become pouring rain.,how long had it lasted,for several days or several months still needs further researches. Flood was washing the surface of earth to form river,lake,and sea ,which make up the important physical and chemical environment for the forming of organic of life,macrobiomolecules, and cell life.
