The world is round because it spins. It spins because of gravity. Think about when you make a ball of dough or clay. You spin it around in your hand or on the table and it eventually turns into a sphere or something very close to a sphere. That's what varying forces of gravity are doing to planets; they "rolling" up different amounts of matter into balls.

The "world" can signify the earth, other planets, suns/stars or even the universe itself.
The "round" can signify a thing without an edge/s approaching spherical shape.
During the formation of the world, it is not solid, it is a form of hot gas/plasma. Gravity is the all-encompassing force that binds everything. Due to this force, everything is all attracting towards its center. When you drop a liquid in space, the simplest geometric figure it can attain is a sphere because any point on the surface of the sphere tends to be attracted to the center equally. When that drop of liquid tends to rotate, the centripetal force makes it bulge at the middle perpendicular to the axis of rotation. This is the reason why the earth is not perfectly sphere but oblate spheroid.

The world (planet earth) is spherical - though not a perfect sphere.
The sphere has the smallest surface area among all surfaces enclosing a given volume and it encloses the largest volume among all closed surfaces with a given surface area. For this reason, the sphere appears in nature: for instance bubbles and small water drops are roughly spherical, because the surface tension locally minimizes surface area.

When everything was gas and our solar system was just forming, the planets finally started to form around the planet and spin do to the pull of the sun and it's mass. This caused the rock to become "round"ish and solid.

it is not absolutely round, more oblate (sort of a flattened sphere)
spinning things tend to become round, because of the tension between gravity and centripetal/centrifugal forces

the world is round because it follows the path of least resistance. that is a curved line

Gravity.
Oh, and seeing as how you said not to give any sarcastic "anwers," can we give sarcastic answers?! :-P

Actually that's a good question. Why are the planets round? I don't know.

The world is not round, it is an irregular oblate spheroid.

So you won't fall off the edge.
