Why do you think packets are broken up into smaller pieces when traveling over the Internet?

Packets are broken up into smaller pieces when traveling over the Internet because it allows the person who you are sending the message to, to be able to receive the full message in an easier way. This is because when sending the whole message without it being divided can cause the message to not send correctly to the person whom you are sending it to, and not only that but it can cross over the Internet slowly.
