Hard not to answer with another question.
1) It wasn't necessarily an apple.
3) Too bad God transcends any ideas of limitations (gravity, "strength," etc.) that we humans can imagine, otherwise, this question could logically prove that God was not omnipotent.
8) Because God was lonely and wanted something on which to shower his perfect and infinite love.
When you get the blanket thing, you can relax, because everything you could ever want or be you already have and are.
