"...We have a "theory of gravity" that predicts the speed at which two objects.."

Sorry, gravity is a law. It's proven to exist. Besides a proper statement would describe acceleration of two objects towards one another in a gravitational field. You need a time variant with a known acceleration to "predict speed".

If you're going to slam alternative theories, such as ID, get your facts straight, first.

"Sorry, gravity is a law."

Sorry, the theory of gravity is just that, a theory. No theories are ever proven in science. If you're going to make statements about science, know what you're talking about first.

Sorry, gravity is a law. It's proven to exist.

Sorry, but you're absolutely wrong. The "law" of gravity show that objects attract one another. The "theory" of gravity (actually, "theories" as there is more than one) attempt to explain why the objects attract.

The law of gravity is simply wrong (Newton's). The theory of gravity (Einstein's) is closer to reality.

You might be thinking of the fact that things fall down. But facts are less reliable in science than theories. There are things that don't fall down. There are things, like the moon, that are getting further away.

Sorry, gravity is a law.

No, the "law of gravity" is a (inaccurate but mostly useful) mathematical relationship defining the resulting gravitational force between two masses. The cause of that force and the exact nature of the force itself is theory.

It's proven to exist.

No, there's no "proof" that the force is actually a direct result of the distortion of space-time between two masses. There's a lot of evidence in that regard, but no "proof".
