One of the things that makes us different from all the other creatures on earth, is our ability to speak. While other creatures communicate in various means, the only creature that can talk is man! And not only can we communicate within our own species, our language can also be understood by other creatures.
Dogs, cats, and other mammals certainly understand some rudimentary parts of speech, but while they understand, they cannot speak back to us.
God gave us the ability to speak to aid in our dominion over all the other creatures on the planet, but it also gives us the ability to communicate own knowledge and memories to other humans, increasing His reach across the whole planet,
And while speech is a great gift, so is Music, which comes tomorrow.
