God errors with an ID I did not touch.

Their is a red line on "android:id="@+id/" " I don't know where it came from.

<TextView android:text="Did You Know?" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/" android:textSize="24sp" />

The actual unique id is the part after the "@+id/" so your id is currently blank, which isn't allowed. You should put a unique id in there like "@+id/whatever_this_is" and the error should go away.

Would it be wise to just delete it?

Either deletion or using Seth Kroger's solution works. It's up to you which one you prefer :)
