If the Earth is moving so quickly, why do we not feel this movement?

we only observe movement relative to our frame of reference.

If you're on an airplane, do you notice the difference between 250 mph and 500 mph? no. if you walk up and down the aisle at constant speed (acceleration = 0) do you notice your movement relative to the rest of the passengars? yes. of course you do.

the earth spins 1 revolution every 24 hours = 24000 miles / 24 hours = 1000 mph. we are orbiting the sun at roughly 1 billion km per 365 + 1/4 days = 70,000 mph. The solar system is sliding through the milky way galaxy at who knows what speed, etc. But that is your frame of reference. within that frame of reference, you're able to see the difference between say walking and riding a bike. a few mph.

why can't you feel this movement? because your not able to compare movement outside of your reference frame. Which is the earth in this case.

Truthfully, movement can only be detected during acceleration or deceleration. So, the Earth is actually moving at a pretty constant speed (although technically, the Earth is slowing down slightly, but this change in acceleration is so minute that the human body does not feel it), and thus you cannot feel its movement.

If you were put into a window-less box in the cargo hold of an airplane, you would not be able to tell if you were moving, assuming that the airplane was traveling at a constant velocity and neglecting air turbulence.

Ignore her, the reason we do not fel it is due to the fact as the earth moves around the sun it also revolves on its axes, which causes the chaning of day and night, and also causes a steady balance of the earth's gravity from the sun, and keeps the world in an equilateral balnce of speed, so its kie if your in a ride that spins around and you spin around with it, you don't feel like its moving as fast.

Because it's not accelerating. If you are in a car going a constant 70 MPH and close your eyes you will not feel movement either. You will only feel it when accelerating or decelerating.
