Evolution question

[Darkstar]

Yeah that makes sense. Because from my understanding, it's impossible for it to be a law.

That would be correct. There are laws of physics, such as

Newton's first law
The first law states that if the net force (the vector sum of all forces acting on an object) is zero, then the velocity of the object is constant. Velocity is a vector quantity which expresses both the object's speed and the direction of its motion; therefore, the statement that the object's velocity is constant is a statement that both its speed and the direction of its motion are constant.

The first law can be stated mathematically as

Evolution can't be stated mathematically, so it isn't a law. Even so, there are theories about laws too, such as the universal law of gravitation vs. the theory of gravity.
