It's about relativity, something you are no where near ready to tackle. Google is your friend, I think even you'll be able to understand this...
How can a plane fly if the earth spins faster?
At the equator, the earth is spinning at 1,000 mph. A 747 cruises around 500-700 mph. How come when a plane is flying in the direction that the earth is spinning, it isn't actually going backwards? (and a side question that goes with this one; how come when you throw a tennis ball in the air in a plane, it doesn't smash through the back?)
Answer - The plane is actually already going about 1,000mph when its on the ground. In fact everything on this earth is already spinning as fast as the Earth is because we're on it. Just like when you're on a bus you're moving as fast as the bus is. When you jump you don't hit the back of the bus because you're momentum is keeping you at the same speed the bus is going.
When the plane takes off it will actually ADD to its already existing speed of 1,000mph and go to 1,500 - 1,700.
