Earth’s gravity influence is much stronger on humans than 2 humans on exert on each other , thus our gravity is too weak to overcome earth’s gravity and pull humans towards each other.
2. Friction
Friction is another reason why humans are not attracted to each other by gravity , The friction of 2 Humans standing nearby are resisting this force but it does little to no job , again because of gravity weakness.
3. Air
Air is matter , so it acts as a barrier that stops humans from being attracted to each other by the weak gravity.
4. Too little mass
The key to gaining more gravity is obtaining more mass , and comparing a human’s average mass to Earth’s , The Earth has a undeniably HUGE mass relative to the human , Thus the earth has a strong gravity , While humans don’t.
