How do accretion discs form in a flat plane around a star?

How does the gravitational order bring matter together in the solar
plane. How then does this matter proceed to become planets?

There were trillions of lumps of matter. How did they come together
for the order of the solar system we now see?

Nobody can do it. And never will.

Gas does not come together.
It dissipates.
There is no way the solar system could have formed,
except by supernatural accomplishment.

Gravity and conservation of angular momentum seem to work pretty well.

Is a fairly reasonable basic introduction to the topic.
