Lets say we moved upwards a little bit in a parachute, then after 12 hours, due to Earth's rotation, we must be above US? (Considering initially we were in India) Answer is clearly NO. Thats because of Earth's atmosphere. It applies force on us and make us move with Earth.

Consider 2nd situation. We are now at moon. No atmosphere! So now can we move just by the above mentioned way?

Gravity is acting downwards! How will it provide acceleration towards rotation of earth?

Sorry. I am wrong. I am deleting my comment.

It's not the earth's atmosphere that's exerting force on us. Actually we are not at rest we are already having an angular velocity which is same as that of earth which will keep us above the same place from where we made the jump.

Also if one would be standing on moon he would only see parachute behave like an aeroplane and he would be unable to appreciate the fact that the parachute just hovered over the moon and reached the other side. The person standing on the moon will see the parachute starting it's engines gaining speed and travelling to the other side of the moon as normal aeroplanes do on earth.
