LOL!!! There could not have been any change in gravity on Earth for billions of years, far-far-far ahead of any life appearing. Gravity is solely a function of mass and the mass of the planet hasn't changed markedly since its initial formation.

No, there was no gravitational change associated with the extinction of dinosaurs.

“Gravity is solely a function of mass”

That’s incorrect. There is also the gravitational constant. Can we be certain that has never changed?

We don't know that for sure.

Suppose the gravitational constant has changed? And the only reason gravity worked is because of trillions of tiny machine guns who's little tiny bullets impacted things on a molecular scale, allowing gravity to SEEM constant, but then Eric Holder banned the machine guns and we needed regular gravity.
