A first concept of this scene.

A view of the early Earth during the late Hadean, about 4.0 to 3.8
billion years ago, the time of the Late Heavy Bombardment (LHB) which
destroyed a significant part of the Hadean earlier crust (according to
modelling, about 25%) and possibly affected early developments of life
in the first ocean basins.

Still visible are a few of the ca 1000 sister stars, born in the same
cradle as our Sun (see Early Earth - The Beginning). Over time, these
stars will be smeared out over the local arm of the Milky Way. Soon
they will merge with the background stars.
