First conact

For centuries humans have dreamed of making first contact with lifeforms from other worlds. So far no contact has been made and humans have spent millions of dollars on finding life from other worlds. The question is are we ready to find life from other worlds? So far we haven't even tried to communicate with other people of our own kind. We can't even accept other people for who they are. All we can do is kill each other for having different beliefs and hold hatred and attack things we don't understand. Then we wonder why other being don't feel safe around us. If even one being was to visit our world people just like now will decide just because they don't understand the other being that it automatically give them the right to attack them.
