For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

How does this affect its gravity?

It doesn't. Gravity is caused by mass not spin. The planet's rotation about it's own axis will create a centrifugal effect that offsets gravity, but the effect is negligible for anything rotating as slow as planets.

It doesn't. Gravity is related to its mass, not it's orbit or rotational velocity.

The others already said the core aspect, but to get specific: the difference between your weight on the pole and your weight on the equator differs only by like .5% or something like that. This is the difference between spinning and not spinning (centrifugal force and no centrifugal force). (And also the difference in radius, since the Earth's rotation makes it a tiny bit flatter than a perfect sphere would be)
