Hi Mohammed, To understand that learn or listen Ramayana. It is not all the Vanaras have put the stone to make the bridge, but it two brothers who had boon that whatever they put in water that will float. So that two Vanara brother's put the stone to make the bridge. Others broght the stones.
Why Ram not made bridge ? It is similar like allah is god for u & who does n't have the shape. If ur god doesn't have shape(physical) & how do you have it. One more thing if God only does everything why it is use of others ? If u ans for the following question will give whether Ram is god or not.
