Most simple (stars planets etc.) celestial objects are round because they were molten once and gravity contracted them symmetrically. Due to their spinning motion they became slightly oval.
Galaxies may assume different shapes which do still manifest some rotational symmetry due to conservation of angular momenta.

The earth is not round. It is considered round because that is what you see when you look at it from the universe. Actually earth looks like potatoe, uneven, when you zoom it. Our earth is not round.

Because gravity crushes things into round things. And if they're super huge like giant rock things, they will eventually be shaped into a circle. That's why you don't see any square or triangle asteroids in space; mostly elliptical.

A sphere is the simplest energy-efficient geometric shape to contain a given quantity of matter.
That's why soap bubbles take the same shape.

Gravity pulls evenly.

they did not start that way ,but the eternal grinding motion of whirling around in space .makes everything into lumpy balls or almost balls
