  Yes, we would affect the Earth’s rotation. It’s just by a ridiculously small amount that nobody would ever be able to measure.

    Now I am wondering how many humans would it take?

      The mass of the Earth is 5.972 × 10^24^, so you would need 5.972 × 10^20^ humans of 100 Kg each all turning in the same direction to make the Earth rotate 1% the other way (so about 597,200,000 trillion humans).

      Whatever amount of people it’d take, the effect we’d make, would cancel at break.

        I was going to say a similar thing, how are you going to get gone without canceling it out.

        But also if you walked away from the equator then walked until you were directly north/ south of your home before walking home, some effect would remain.
