mankind has this wish to contact aliens on other planet, presumably super advanced aliens with starships able to warp to earth and say hello, pity mankind can believe in aliens but can't believe in God....huh. oh that's religion right unless its aliens and then we can believe..that they are aliens who want to impart super knowledge, not moral understanding. But lets assume there was no God, just for a minute, just aliens. What do we know about aliens? well nothing..except if we look at ourselves. So lets look at Earth as an example of what aliens will be like, they are warlike, kill one another, destroy, abuse, pollute, rape, get the picture, so we want to contact aliens who most likely are like us and will invade the earth and cook humans on the BarBque on Saturday afternoons? Even if we look at the animal kingdom its all dog eat dog man, there are no little green men out there living in peace, Say no to aliens don't invite them here, thankfully the earth is protected by God even if he made aliens.
