Sadly by that time the actual surface of the Earth is more than 2km below the hypothetical plane the ball bounces along. Of course another answer might be 490 bounces, or 489 bounces and one hitting the ground and rolling.

Surface area of all land on Earth: 148.3e6 km^2
Surface area of one human (very conservative): 2 m^2
148.3e6 km^2 / 2 m^2 = 7.415e13 people needed to cover the surface of Earth's land.
So the probability of hitting a person, assuming the ball is launched from a random location on land and all dead humans are randomly scattered across the land mass of the earth is: 7e9 people on Earth / 7.415e13 = approximately 0.01% chance of the bowling ball hitting a body on its first bounce. The earth isn't really littered with bodies, and I'd give this answer no credit.

If there is air, there is air resistance. Therefore, If there is no air resistance, there is no air.
