The singularity:
At the beginning the gravity was so great that time was very slow in
fact theoretically it is infitely slow. The universe came out of this
still time.

In the beginning the expansion or space-stretch required to overcome
the gravity moved matter faster than the gravity could slow it down.

The space stretch doesn't slow time. Distant galaxies are not moving
through space so they cannot be said to have slower clocks. They may be
said to be redshifted but that is due to the space-stretch. Still the
beginning is a stillness of time or singularity.
