theory of extraterrestrial life?

out of all of humanities worries one of them is life on other worlds so far people are divided on where humanity came from and our purpose some speculate life exists and some dont honestly of course it exists if not we would be a lonely species so alone among the billions of stars humanity isnt alone but its still to primal to be able to meet any diplomatic means from other species so they watch we are a judgemental species and sadly we cant travel the stars yet but other species exists some warlike some peaceful some humanoid some symbiotic some mechanical to discover other species meet new allies new enemies if humanity keeps like it is we will never be able to enjoy the vastness of space....

out of all of humanities greatest achievements none are good enough to bring us allies from beyond .... all we do is bicker and fight like children instead of work together maybe that's why they dont interact much because were very..... warlike but my theory is if humanity swept aside its differences and worked together technological advancements would come faster and easier and if we were invaded? humanity would need to be one instead of divided as many to get what humanity has always sought..... peace and knowledge comes to a world as one but aliens arent keen on being experimented on although I would happily enjoy being a part of an advanced future
