Inertia does not make ANY sense. Can someone explain to me how the fuck can such thing exist in nature?

Think like this:

>My hand (a bunch of atoms) is moved, and displaces other atoms (an apple)
>This displacement (my hand atoms bumping into the apple) causes the apple's atoms to be displaced, so it moves
>as soon as my hand stops displacing things, the atoms on the apple should absolutely fucking stop - because there is NOTHING exerting force into them anymore. There is nothing cause their displacement

Instead, what we are saying, is that "oh well, you displaced these atoms, now you have flicked this switch on those atoms that says "keep going to a direction forever, lol", and every update of the universe's framerate, those apples keep moving because we turned on that switch.

What the fuck, this is absolutely insane. What is a theory of what the fuck is inertia? The idea of "things just keep moving once displaced because why not lol" is insane, if they are being displaced even after my hand stops displacing them, something is causing their motion, its a perpetual energy being given to that apple to displace it.

What is this energy? What causes that continuous, eternal motion?

This is bullshit.

If the bus guy jumps, he should immediately freeze in the air, he should not move forward with inertia forever, because the bus nor anything else is no longer displacing him.
