Generally, atoms of a substance vibrate in their positions. Temperature of a substance is directly related to this vibration velocity.

temperature is not a measure of speed, temperature is the average heat energy in a substance. As heat energy increases, speed of the ATOMS will increase, and make them expand, forming a liquid, or a gas.

Heat is not a direct measurement of speed. It is a measurement of energy, which is proportional to velocity.
Saying cold is not real is like saying darkness isn't real since it is the absence of light. If you were in a temperature of say -100 degrees celsius, I guarantee you wouldn't be saying "its less hot".
It is not correct to say "cold is the absence of heat", since heat is just a concept made up by humans. Heat is change in energy, we just associate "hot" with something that has more energy and "cold" with something with less energy.
Heat always flows from hot to cold.

Simple. Look at it this way: "Cold" isn't something real - cold is actually a lack of heat.
To make heat, atoms have to be moving... the faster atoms move, the more heat is generated (usually.)
