From newtons third law we know one thing. Every action has an equal and opposite reaction. This means that the force we act on earth is equal to the force that the earth acts on us.

This means

f = ma ( by person )

The average mass of a person is 70 kg and acceleration due to gravity is nearly 10 m/s^2.

So the force we apply on earth is nearly 700 N.

Now

F = MA ( by earth)

The aproximate mass of earth is 6 × 10^24 kg. But the force remains 700 N

Now A = F/M

A = 700 / 6* 10^24.

=> ~ 116 * 10^-24 m/s^2.

That acceleration applied by one person is so miniscule that it does not need to be considered.

The acceleration of earth is in negative powers of 24 . So we need more that just billions of people to accelerate the earth upwards.

From Newton's third law, we know one thing: every action has an equal and opposite reaction. This means that the force we act on earth is equal to the force that the earth acts on us.

This means $$ f = ma \rlap{~~~~ \left( \text{by person} \right)} $$

The average mass of a person is $70 \, \mathrm{kg}$ and acceleration due to gravity is nearly $10 \, \mathrm{m}/\mathrm{s}^2 .$

So the force we apply on earth is nearly $700 \, \mathrm{N} .$

Now $$ F = MA \rlap{~~~~\left( \text{by Earth} \right)} $$ The approximate mass of Earth is $6 \times {10}^{24} \, \mathrm{kg} ,$ but the force remains $700 \, \mathrm{N} .$

Now $A = F/M$ $$ A = \frac{700}{6 \times {10}^{24}} ~~ \Rightarrow ~~ \sim 116 \times {10}^{-24} \, \frac{\mathrm{m}}{\mathrm{s}^2} \,.$$

That acceleration applied by one person is so minuscule that it does not need to be considered.

The acceleration of Earth is in negative powers of $24 .$ So we need more that just billions of people to accelerate the earth upwards.
