Elements:\n\nMain constituents are H, C, O, N, with considerable amounts of Ca, Na, P, S, Cl, less Mg, K, Fe, I, and traces of about any common element.\n\nThe most common simple molecule is water.\n\nMost important "inorganic" compounds are CaCO3 (in the bones), NaCl (dissolved in the water) and Ca2(PO4)OH in the teeth.\n\nThe main classes of chemicals are carbohydrates and proteins, which form the main structural elements of our cells as well as most of the functional framework. (DNA for instance has a modified carbohydrate linked by phosphate as its structural basis). Fats (triglycerides of fatty acids) are abundant, but don't participate structurally in most features of human anatomy except as fillers (lower skin, lips, breasts...)

Every where chemica reactions occur to regulate life processes, within your body millions of chemical reactions happen within a second so that you are able to function. Put that on a more macro scale say the environment, everything from water breakdown, decomposition, geologic formation, life cycles, etc are all governed by chemistry. Suffice to say that life would not be possible unless chemistry is relevant and working.

ATP maybe.\nGlucose if not.

The chemistry of a perfect life would be one where all the metabolic processes are well regulated and where the chemical pathways of energy production are not futile, but rather very efficient. This is hard to find. The human body was made to resist changes despite the outside environment and being perfect at a certain time would probably mean there is not external factor that affects calls for homeostasis, which is pretty unlikely.

Unable to guesstimate.  You're talking biological macromolecules, most likely.  They would probably have carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus, and perhals a halogen or two.  And maybe even a metal ion or two thrown in for good measure.

as humans we are carbon based but in order to live we need Oxygen\n\nYeah I think there are millions of things out there living on other gases.

1.Take in nutrients (humans from food, trees from the sun)\n2.Grow\n3.Breath (humans take in Oxygen, trees take in Carbon dioxide)\n4.Reproduce (humans have children, trees release seeds)\n5.Excrete wastes\n6.Die

It is the organic processes (in a cell or organism) that are necessary for life.

humans and most lifeforms are chiefly made of water ( 98% ).\n\nthus, the principal components are HYDROGEN and OXYGEN.\n\nProteins and Fats comprise most of the remaining substances ( muscle and flesh ).  the main atoms here in addition to the above are CARBON and NITROGEN.\n\nOther elements (atoms) include CALCIUM ( bones ) and SULFUR ( hair ).\n\nTrace elements ( very little < 0.1 % ) include IRON ( blood ), PHOSPHORUS ( bone ) , and MAGNESIUM.\n\nThere is even COPPER, ZINC, and GOLD ( extremely low ) present in certain enzymes  in order for them to function !\n\nhope your question was answered !

oil, coal, natural gas.\n\nancient plant matter.\n\nIt depends on how old the human is. An adult has 206.\n\nIt isn't. But it might be just as bad, depends on the chemical and the duration and level of exposure.\n\nHuman Immuno-deficiency Virus.

There is no real model yet for the origin of life. However a number of discoveries have been made concerning the origin of molecular and cellular components that are necessary for life on earth:\n\n1. Conditions that existed 4.5x10^9 years ago result in the creation of certain basic small molecules of life, such as amino acids. This was demonstrated in the Urey-Miller experiment in the 50s.\n\n2. Fat molecules can organise spontaneously into layers which form the basis of cell membranes.\n\n3. Amino acids polymerize spontaneously into random RNA molecules.\n\n4. The resulting molecule soup will compete for resources, by which I mean smaller molecules, to be able to grow further. Therefore there will be selection pressures for efficiency and diversity which will favour those macromolecules that can reproduces themselves or part of themselves most quickly and efficiently.\n\n5. Thus evolution begins: once certain molecules are formed in the soup that can reproduce itself partly, they will soon dominate in the mix. In the next step the *better* ones among those will be selected and so on.\n\nTo summarize:\nWhen: between 4.5 and 2.5 billion years ago\nWhere: in water ponds at the surface of the earth\nWhy: any mixture of organic molecules will change into a mix of more complex molecules by polymerization\nHow: Selective pressure will favour those molecules that react faster and more efficient.

Not God. When life is broken down to its most basic funiction it is nothing more chemical reactions. Something that simple multiplied enough times can lead to complex forms of life. Just look at a computer. Its basic function is a 0 or a 1, On or off, yet look what it can do.
