Move is relative.
Does your train move? Or the one next to your train?
Are you running? Or is the whole Earth moving under your feet?

You put your keys in the pocket.

Or do you... move the Earth, the people on it, the solar system, the galaxy, the whole universe so as to make the pocket "engulf" them?

The latter seems impossible.

And yet, we do it!

Two possible choices here.

We either do not do ANYTHING at all. [Zeno-like skakos paradox]
Or we... move mountains and whole planets every day.

Your choice. Make it an interesting one!
