Probably for the same reason that we THINK that GRAVITY pulls downward.....

Acceleration is the change in velocity - not speed. Velocity is a vector and is characterized by magniture (speed) and direction. Traveling in a circle (even at constant speed) requires a uniform change in direction. That accelration is always normal to the direction of travel, which is why it can change the direction of the object, but not the speed.

it is accelerating toward the center. If it were not accelerating it would go in a straight line at a constant speed.

Its angular velocity keeps changing so it is said to have an accelarating force.
Its direction changes with the position of the body.
The direction at a particular point is given by the tangent drawn from that point in the direction of the force.

its speed is constant but velocity is not because its direction is always changing. change in velocity is acceration, so it is considered accelerating.
