@botarakutabi1199 Exactly, engineers used strings, ropes, grips, wheels, boards, water, sand, plum stones, and most importantly, all kinds of levers, plus other nifty tricks, to make labor easier... but you still need to get energy somewhere, and without a motor converting fuel (steam, coal, oil, electricity whatever) into motion, you have to use human power.
