I believe in extraterrestrieIs, but I personally don't believe in alien aircraft being around Earth. It would just be a waste of their time studying something so 'primitive' compared to them.
I totally 100% agree with you.
If there is life in the universe I highly doubt they would take interest in a barbaric, primitive species like us.
Collectively, humanity is a parasectic to the planet, we're territorial and violent, we create religions to give answers to questions we can't answer or can't understand, We've only been able to send machines within our own solar system. Bottom line, we're not ready for extraterrestrial contact.
If there is a species as intelligent enough to travel through the galaxy at speeds we cannot imagine, I highly doubt they'd be interested in Earth. I also believe that their interests in our planets resources, human intelligence and our methods procreation is minimal.
With the level of technology and sophisication that it would take to get here from out there we wouldn't stand a chance however, species that evolved would not be hostile.
