Because at one point in time, the earth was a liquid. Liquids in space for spheres because of surface tension and gravity. Then, over the years, the earth cooled in the shape of a sphere.

The Earth Most Probably Was A Uneven Lumb Of Hot Moten Lava And Rock, With The Roation Of The Earth In Orbit, It Slowly Shaped In To A Perfect Sphere....Now With A Protective Layer Around The Earth, Changing The Shape Is Up To Man Kind - Bloody War Lovers

If this world is square then they will ask why is the world square and not round. You will never get the right answer. God created this world, he should know what's best.

The world has no form so it is not round nor square. Form, colour, taste, etc. are properties of some things that can be considered "of substance". Obviously, the world is too complex to be considered "of substance" or even "material". To declare it "round" is faulty - to the same degree as to declare it "square"!

OMG this is so stupid and its FUNNY
ITs like saying or asking
How come a balloon is round and not square?
HAHha
im not an expert or anything
but if the world was square it wouldnt beable to rotate its course around the sun .. it would jus flow into outter space and hit a comet already

Part of the definition of what it is to be a planet is having sufficient gravity to hold itself together. Gravity is a force that does not have a vector (direction) so that it works equally in all directions.
Spinning on an axis is actually affecting the spherical shape. The earth is wobbling in three different ways, changing the earth's shape.

The earth is round and not square so we can make fun of the people who claim it is flat. If it was square there would be eight flat sides and then they would be making fun of us that believe it is round.
It is also round so Columbus would be able to find the New World.

Planets (...and also stars) form within immense drifting clouds of gas and dust. Every bit of gas and dust generates a tiny gravitational force. In relatively dense regions of the drifting cloud (...called a 'nebula') two or more bits of gas or dust may be close enough so that they're attracted to each other by their gravity. They clump together, which increases their overall gravity. This larger clump is surrounded by more bits and pieces which are drawn in from all directions. The original clump grows in size and produces more gravity, which in turn pulls in even more material from all directions. The result is a growing sphere.

Take a square of cookie dough and put it on a platter.
Now spin the platter really really fast.
You'll see that the cookies turns from a square to round.
The earth is spinning and has been for billions of years.
It isn't completely spherical, but the lumps are pretty small,
by comparison to its size.
It is currently an "oblate spheroid" (squashed sphere).

I do believe the answer in this one has to do with the surface area of liquids. If you research why liquids (when in vacuum) take a round shape, you will get your answer of why planets are round and not square.
