>>21820301we have always been on Earth's speed, so we can't notice the change (so when you step on a spiny thing you do feel the change in speeds) plus there's this invisible thing called air that's all around us? you breath that, anyway, to move you must move through the air which acts as a fluid so that adds to the feeling of moving (there's no air in space, if you want to test that out by yourself go for it)
