Because air preasure is distributed evenly and in all directions. Notice that if you blow on a bubble it changes shape temporarily, but only as long as the preasure on it is from one side. After you stop blowing it returns to perfectly round.

Cause the bubble want to collapse it's total area while the air inside it want to expand. A sphere the best common solution.

bubbles can be any shape!!!! They just conform to the " container " that defines them. You must be thinking of a floating bubble, which is a sphere because it's only container is atmospheric pressure. ( General law of dynamic equilibrium ).

the air pushes out in all directions but gravity is also pushing on the bubble therefore you get the round shape

a sphere represents the "lowest energy" state for the air/water interface -- the very least surface area to contain the most possible space (air in the bubble).

Because the round shape offers the least resistance and occupies the least space to contain air.
Physics tend to adjust the easy way in their shapes.

because that shape is required structurally to hold them together. It has to be oval as the sufrace tension demand it, when the surface tension becomes uneven it will burst

Spheres provide minimal surface area.
That was the best I could get

Spheres minimize surface area while maximizing volume.

cuz there filled with air and pressure hits it in all sides so it turns
into a cirle
