How can galaxies rotate coming from a singularity?

You apparently have a misconception of what "singualrity" means and you think it means a point in space where things came from. Even in pop-science it is not stated that galaxies came from a singularity but it is stated (incorrectly) that the universe exploded from a singularity.How did you find PF?: Google search

It is explained by Conservation of Angular Momentum.How can galaxies' rotation be explained?
nothing - the universe is not rotating - you seem to have reverted back to thinking that the universe "exploded" from a point in space.What does this principle mean for the whole universe with its billions of rotating galaxies?
nothing - there was no rotation at the beginning - you seem to have reverted back to thinking that the universe "exploded" from a point in space and was somehow rotating then.And what does it mean for the state at the very beginning?
There is no such principle. There is conservation of angular momentum, but angular momentum includes more than just spin around centers of mass.Your answers are not compatible to the principle of spin conservation.
I think you are confusing the angular momentum of an individual galaxy and the total angular momentum of the Universe. As far as I know, there is no evidence of any net angular momentum and no evidence of a 'preferred' axis but if you start with a sample of primordial gases (the future galaxy) then that sample would be expected to have a non zero angular momentum and some preferred axis. The rest follows.the real question remains unanswered: How can galaxies' rotation be explained?
