When you ask why was there an expansion or why the universe exists, it's nearly the same as asking why there are snowflakes, why do stars give off light, why is there gravity ?
Imagine a cloud forming in winter. It's loaded with water vapor and the temps drop. Snow falls and from your bedroom window you see the light bouncing off the snowflakes.
For a second the world is magical.
Can you see the analogy ?
The forces of the universe changed in such a way to cause energy to expand out and galactic snowflakes were formed.
It's not a perfect analogy but you can see it right ?
