So, I was thinking...
You know how the earth rotates and spins upon its axis?
If you think about it, since we're constantly rotating and spinning, at any given moment, we are in a different point in space in which someone else from somewhere completely different stood, or walked, or slept, or cried, etc. Who knows? You might be where a mountain once was at that point in space.
Granted, this is an utterly useless thought, but just wanted to share
