If there was no friction then we could not walk, we would keep slipping.

Nothing would be steady on the ground, many things would be just sliding

and sliding. Nothing would exist in the way they do now.

You could not pick up a glass with a drink in it, you could not hold a pencil,

a leaf, a spear, or your cellphone, and you could not turn a page.

It seems unlikely that we could exist at all.
