Today, if someone were to create a large message, or spread news, they'd have many options of communication. Again, 10,000 years ago, this would've been much more complex. Aside from Egypt, which had their ways of communication pretty set, other places like mesopotamia were struggling. With the unpredictable weather, which led to a small amount of resources, they were never prepared for a fight. Having hardly any gear to fight, and only few crops, there wasn't much of a chance that mesopotamia would survive as a whole. Communication back then, would've been a great help for the well being of us humans. When you think about it, a simple message from Egypt could've even been helpful, but the distance of the two civilizations was inconvenient.
