Why is liquid hard to compressed?

This is ultimate question! Sincerely I do not know the answer. I always wanted to know the answer. Now comes a pure guess work. Most of the solids can be compressed in day to life. Because there is gap between the molecules. Some solids are really solid and they can not be compressed. For example the gold. But usually such solids are usually formed from liquids getting cold and turning into solids. Gas can be easily compressed to great extent. But then there is limit to it. I believe than if you compress gas with too much pressure, it should turn into liquid. For example oxygen or nitrogen. But still the golden question remain unanswered. Why the liquid is hard to compress? So there has to be special type of bonding in the liquid. Here the molecules are attached to each other, so that a particular and only particular distance is maintained at any given temperature. If you increase the temperature, distance increases between the molecules. Only the notable exception that strike to my mind here is water molecules. Water molecules contract till 4 degree Celsius. Then start expanding till zero temperature is achieved. (Every body knows the implications of this anomaly on the life at polar regions. Life can sustain below the ice due to this anomaly and due to bad conduction of heat by the ice.) So there is special type of bond between liquid molecules. Which allows the fluid to to take any shape. This bond can be broken very easily. It also allows dissolution of many substances in the liquid. That means there is gap between the molecules of the liquid. Now your intelligence stops there and there only. (I personally has no doubt that the designer has designed the anomaly of water to make the life sustain at polar region.The same designer has designed the laws of nature.)
