Nothing pops up without raw material. Everything we see and touch is a compounded matter and an attribute of compounded matters is the life span its nature allows it to exist. How did the universe arrived to its present size when it used to be just a dot. That dot was composed of solid material or element. It exploded due to the imbalance in density between the solid dot and atmosphere around it. As the fragmentations resulting from the explosion are propelled and spin they draw the elements enveloping them; these elements are what we refer as dark matter. But where did the dark matter come from? When the life span of a celestial body ends it would release the elements composing it. These elements are the same elements that the next arising body would be made of. Dark matter is everywhere including earth. The mushroom that spring during thunderstorm are the same dark matter that celestial bodies are made of.
On the other hand, dark energy is explained by atomic vibration. The mechanism that makes an atom to vibrate is the same mechanism that holds celestial bodies together. The key in understanding dark energy is the fact that size is a matter of number, meaning the large the body the more atom composing it. An imperceptible atom is made of few number of particles compared to a galaxy that is composed of countless number of atom. Size does not matter, the law governing an atom and a galaxy is the same. The only difference is magnitude, i.e., small atom vibrates rapidly and a galaxy has immeasureable vibration (life span).
