Genesis 7:23

And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.

1. Really, all living things upon the face of the earth - human beings, cattle, creeping things, birds - they were all killed. Only those in the ark survived.
2. This was not a local event. Only Noah and those in the ark survived it.
