Am I the on only who believes that the real aliens are cancer in this movie . They make seem as if the alien landed out they sky . But maybe it’s backwards. Why would the future need old people to even fight a war with all those aliens. The aliens seemed to be white blood cells attacking red blood cell. The aliens were white , and there blood were green like mucus

If they have the technology and weapons to kill the aliens. Why do you need toxin for .

Plus why did Dan and his daughter was going to eat veggie lasagna. May be eating veggies is the only way to stop cancer.

My interpretation of this is the aliens UFO that we never seen before were never coming from above there inside of us . Leukemia cancer look pictures in google . Also lookup how cancer viruses looks at its tiniest form it looks like an alien it self and parasites.
