ruby on rails チュートリアル 2章 herokuにpushでエラーが出ます。

プログラミング歴　１ヶ月の初心者です。

２章の下記で詰まりました。
herokuにpushできません。

$ git commit -am "Add hello"
$ heroku create
$ git push heroku master

やったこと
試行錯誤してよくわからなくなったので４〜５回、bitbucketとherokuのリポジトリを削除してやり直しました。完全に消えたかわかりません。まだどこかにデータが残っているのかもしれません。

どなたかherokuにpushできる手順、エラーの原因を教えていただけませんでしょうか。よろしくお願いいたします。

以下、コマンドラインです。文字数オーバーしたので「・・・」は問題なさそうだったので省いています。
