A childhood belief about physics

I was told once (by whom, I can't remember, but it was someone important: teacher, parent, etc.) that the reason we stay on the earth's surface and do not float away into space was because of the earth's spin. I found out much later in life that mass has gravity.

I would rack my brain trying to solve that puzzle. If I spun a plate, everything flew off of it. Only when it sat still did everything stay. It made no sense, but I believed it because I had no other explaination.
