I mean the Hive build a massive vessel the size of Earth’s moon that is capable of wiping out the entire Awoken fleet. Also the Dreadnaught can defy the laws of physics and somehow not destroy Saturns rings even though that would absolutely happen if you placed an object that massive in the rings of Saturn. The use of magic and the ability to create throne worlds isn’t entirely unique to the Hive, but consider this: when you understand something you call it science, when don’t understand something you call it magic. We consider the Hive to use an advanced form of magic, suggesting there’s a lot humanity doesn’t understand about them.
