Because they both flow and can change shape
What kind of fluid, liquid or gas? Gases are compressible, liquids pretty much are not. (And yes, both gases and liquids are fluids; the word "fluid" comes from the same root word that gives us "flow," which both gases and liquids are capable of doing.)
All I know is that we drink liquids, breath gases, but how does solids help?
This variation is typically small for solids and liquids but much greater for gases.
because liquids can give us the right temperature but solids and gases
the kinetic theory of matter says that all matter is made of particles that are in constant motion. Matter is made of constantly moving particles, which tells us how the matter in solids, liquids, and gases behaves.

Fluid dynamics, fluids make good coolants, its viscosity can fill any shape. I am sure there are more....
The gas all around us is simply referred to as "air". It is composed of 78% nitrogen, 21% oxygen, and 1% various other gases (water vapor, trace gases, etc.).
Radiation in heat transfer is one of three known modes of heat transfer: conduction (as heat transfer in solids and less effective in liquids)), Convection (as in liquids and gases), and radiation (that not necessarily require a medium for the transfer). Heat of sun is transferred to us in the vacuum space by radiation heat transfer.
The gases that are around us are 78% nitrogen, 21% oxygen and 1% carbon dioxide, argon and other gases
Your question doesn't provide us with the terms so there is no answer.
There are many reasons why gases are important to us. For example, the air that we breathe is a gas.
