We were curious: what are watermelon rinds good for? So what benefits does it give the watermelon? Why did mother nature give it such protection?

You have answered the question yourself: it's protection.
Melons have originated in what is today South-Eastern Africa and Western India according to this source. In a hot and rather dry climate having a watery fruit can bring an advantage to the seeds (helping them to sprout in an otherwise dry soil). At the same time, any source of water would attract animals eating the fruit. A shell would protect the seeds during the ripening process like the shell of a nut prevents it from being eaten.
On the other hand, animals eating the melon might actually be desired, since fruit eating herbivores help spreading the undigested seeds. The shell would then especially protect the watery flesh from water evaporation or predators who are not helping to distribute the seeds. A ripe melon opens up and releases the seeds from their protective shell.
