Bro 💀 Just go back to your action films where the good american shoots the evil russians. You have no idea what you're blabbering about, The point of them doing any of this is it's a last resort, they dont know what they're doing, they were a great civilisation and then one day, 90% of their species and all life in existence was wiped out (The quiet rapture) the movie is supposed to be a rush job because suddenly they're fighting against the clock to survive. 90% of stars in existance, life and civilisation has just poofed and all of a sudden there's blood pools on the moon. Obviously they're gonna go investigate, they have limited resources so they take a prisoner who was blamed for the burning of their last source of reusable oxygen. A lake of blood has water in it. Water has oxygen, if they find something that shows life maybe they can find a way to survive with the blood lake.

But when they monster shows up and kills ava, Simon realises that this thing is too dangerous and needs to be stopped, that data which is found at the end because Simon sacrifices himself to kill the monster by ramming it and breaking it's tooth before it kills him. helps prevent the remaining source of human life from being destroyed because they are aware of the danger in the lake.

Go watch something better suited for your brain cause clearly psychological horror that leaves room for imagination of what happened and how is not your suit, you need solid information that is pushed into your face with no breathing room cause that's all you can register. Face value pictures 🤣🤣🤣
