Reply to comment by in ELI5 Why when we jump in the air the earth doesnt move by

So everything we have been taught about jumping is a lie,is it just forward momentum?

No. You are jumping up, but also moving sideways at a speed basically equal relative to the Earth's rotation.

You are already moving at that speed, as is everything around you, including the air (assuming no wind), so from your perspective, all the motion is up/down.
