Maybe from laughter. That would be a sight, wouldn't it?
But no, people are scattered over the earth so there is not enough momentum or kinetic energy in any spot to crack the earth. If every person was in one small place and jumped at the same time, they might cause a local earthquake.

Nope. There are approximately 6 billion people in the world. Let's say that each of them masses 75 kg (165 lb).
6 billion * 75 kg = 450 billion kg or 4.5 * 10^9 kg
The mass of the Earth is 6 * 10^24 kg.
That's a ratio of approximately 1:1000000000000000
That's somewhat smaller than a mosquito trying to move you by landing on you.

no, we would still be too light even to make a hole the size of a car
