In this scenario an advanced race of Aliens with a tech level similar to what we see in Star Wars decides to invade our world. They had seen many of our media over the years that was broadcasted into the greater galaxy and deduced we would be easy to conquer. So they sent a massive fleet of ships and troops to conquer Earth. But when they arrive here to conquer us. They realize how off their calculations were. They thought like all other races they they encountered that we were the same size as them. But as it turns out by Galactic Standards. Earth Lifeforms and Humans in particular are freaking Kaiju sized. We are the same size as many of their combat ships. Individuals of their race are only 1 inch tall. And despite how advanced their tech is only their starships can take on a full grown well armed human. And even then we can destroy their ships.
So with the die cast they attempt to establish a beachhead on Earth. Their invasion fleet is only 50,000 ships with the largest being the size of a Pickup truck. They have blaster technology and their missiles are about as powerful as a really strong grenade. They have initiated their invasions in Central America, Africa, France, Vietnam, Texas and Australia. How does the war go for them. Well they be forced to flee from Earth.
