Well, there was some energy, that we assume canceled and cooled from BANGBANG or some infinite energy fluctuations that took place in a spacetime 13.8 billions yrs ago, btw I also need you to accept that spacetime only moves forward.
Now let me tell you about the accidents that happened after that energy cooled and canceled into a configuration that allowed galaxies to be formed in spacetime:
*4.9%(matter) of that energy gravitated in spacetime and used other forces and things to turn into atoms and galaxies,
while 26.8%(dark matter) of it was energy only and only to gravitate in spacetime which let that 4.9% form galaxies around it,
the rest 68.3%(dark energy) of that energy was only and only to stretch spacetime to let that galaxies form in the universe.
