No, it is not true that changing the shape of any natural thing, such as the moon, would cause it to die out soon. The moon is a natural satellite of Earth and has been orbiting our planet for billions of years, and its shape has changed over time due to various factors such as impacts from meteoroids and the gravitational pull of Earth.
The moon's current shape is determined by its mass, gravity, and the forces acting upon it. If the moon's shape were to change significantly, such as by artificially altering its surface or changing its orbit, it could have an impact on its gravitational field and tidal forces, which could affect the moon's geological activity and potentially lead to changes in its surface features.
However, the idea that changing the shape of a natural object will cause it to die out soon is a generalization that does not apply to all natural objects. The lifespan of natural objects depends on a variety of factors, including their composition, environmental conditions, and interactions with other objects in their environment.
