My life is like a battleground. By this, I mean there is always an ongoing war between creatures of various cosmos's, and soldiers can suddenly seem overwhelmed when everyone is trying to kill them. I've got a friendship-group that I'm trying to convince that the humans are going to win. The only problem is that I'm outnumbered around 3:1, and I have nothing to back up my points with. You know how hard it is to convince someone who doesn't have hope left, right? That's why I need your help. Below are a list of genuine quotations that I've had to defend myself against in the last week or so - relating both to the casulties and the victories of the earth. I've managed to hold my ground so far, but it's getting more difficult by the minute. How can I respond to these statements?

"Aliens look much bigger [Size] than Humans"

"Big Guns result in Casulties; like the Destroyer"

"Pyrotrone is a minigun"

"The Human forces are almost completely made up of amatures"

"Steel Batallion is a MechWarrior, and a badass one at that"

"Humans are dying, and will extinct like Dinosaurs"

That's all I've got so far, but if I get hit by aliens, Hopefully i can report it here. Thanks for the assistance, comrades.
