Motion is relative. If you were travelling at a million km/hour, the statement with be meaningless, it's stated relative to what you were travelling at that speed. it is quite possible that relative to some objects in the universe that we are travelling at millions of km/hour.
I’m not saying with absolute certainty whether the Earth is flat or a sphere. I understnad that you got your information from the Bible that the earth is flat. Are you now saying that you are not absolutely certain that the Bible is without error?
