Eli5: In Flemings Left Hand Rule, what does Motion mean? The current direction and Field i understand but I’m so confused on where Motion is involved.

Think of it as “force”, not “motion”.
Given the particular current & field direction, the conductors is going to experience a force in the direction given by the rule. Since Fleming’s rules are for things that spin (motors/generators), you can safely assume that the rotor is going to move in the direction of the force unless something is holding the shaft. Hence “motion”.
