There are a couple reasons. Just like making tea, you start with cold water because it is clearer. Hot water comes out of the tap foggy. The more important reason is that cold water doesn't immediately cook the proteins.(like blood in the marrow of the bones) It allows them to float to the top where you can then easily skim them off.
Your ingredients should always be covered in cold water. When bones are covered with cold water, blood and other impurities dissolve. As the water heats, the impurities coagulate and rise to the surface, where they can be removed easily by skimming. If the bones were covered with hot water, the impurities would coagulate more quickly and remain dispersed in the stock without rising to the top, making the stock cloudy. You should simmer a stock gently, at about 185 degrees. Start from cold to hot, not warm to hot. It will ruin a stock.
It brings out the maximum flavor of the ingredients and prevents the stock from turning cloudy.
No, all stocks should be started using cold water.
If you simmer the stock and evaporate some of the water, the flavor will be concentrated and it should taste better.
they made them when there was water
