A deer in a forest with trees and fog

The universe is a dark forest，Every civilization is a hunter with a gun，Sneak like a ghost through the forest，Gently pull away branches that are blocking your way，Try not to make a sound in your footsteps，Even breathing must be careful：He has to be careful，Because the forest is full of hunters who sneak like him，If he finds other life，There is only one thing that can be done：Shoot to destroy it。. In this forest，Others are hell，It is an eternal threat，Any life that exposes its existence will soon be wiped out，This is the picture of cosmic civilization
