Do you remember the first time you did something your parents asked you not to do? Did you get caught? If you did get caught, how did you handle the conversation with mom and dad? Adam thought he could stay under the radar when he disobeyed God. Just like a parent calls out when we goof up, the Creator came searching and asked, "Adam, where are you?"
It really doesn't matter how old you are. If your parents are still alive, they will seek you out if you haven't been in touch in a while.
God always knows where you are. He asks you where you are because He wants you to be aware of how far away from Him you are. The further you stray, the harder it is to hear His voice. Remember this: You are God's child. He is seeking you. He wants to be in a relationship with you. He doesn't care if you ate the apple when He asked you not to. He doesn't care about your mistakes. He only cares about being with you. He loves you. All you have to do is turn around and go back to Him. Everything is forgivable.
If you are having trouble finding your way back to God, read this verse. It's one of my favorites because it reminds me God sent His only Son to help us find our way back to our Creator:
For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord ~ Romans 8:38-39
