What was the first word spoken by man?

We do not know the first word ever spoken because, in the Bible, Adam named all the creatures and animals (Genesis 2 verse 20). The first word ever recorded was "This" (Genesis 2 verse 23)

That's easy. You can say it now. Just open your mouth and without moving your lips make a sound. There, now doesn't that make you feel better. aaah, that wasn't so hard, was it? Ha! Oops, that one came later.
