I think it's presumptuous of humans to believe we are the most intelligent beings to exist. I believe God created the universe and there are limitless possibilities of the types of beings He could have fashioned. I just don't think that we are meant to find other intelligent beings until we can live and get along with our own kind and care for the planet we already live in. Maybe it's for those ET beings'protection more than for ours. Great question!
Well, the fact is, if aliens are real, it would take a heck of a long time for them to get here. And we haven't even gotten as far are Mars other than an unmanned robot. The sheer space between us makes such a meeting pretty unlikely, until we can go a LOT faster.
because it would be like me hearing scottish ants to come and check out there anthill for that is prolly how the aliens would see us for earth was made 3 billion years after the big bang and humans have been around for nearly noyhing well our species anyway, so they would be so advanced it wouldn't be worth there time.
