Why is gravity so strong to hold people, buildings and the oceans stuck to a spinning ball-Earth, but weak enough to allow balloons, birds, bugs, flowers, and smoke to easily rise against its awesome force?

You're not a physicist are you? Most of these don't even warrant a response but smoke and the gas in balloons are lighter than air so they float. And if birds didn't flap they'd soon meet the fate of gravity.

Nope they meet the faith of density like everything else. To make things easy for you. Gravity is simply density and buoyancy.
You are more than welcome to quote every single point.

Gentle lift of and gravity.
