I feel the same however my argument to him was surely not everyone over the last 100 years or so of recorded 'sightings' is bullshitting and not everyone has doctored photographs or film. It's a strange one.
We were talking about the sightings and "size" of craft and why indeed "UFO's" would be so small considering the distance they would need to travel. I said we don't go round exploring in jumbo jets, most of our reconnaissance missions done these days are done with drones. His response was this
For me to believe we are the only form of living existance in the universe is a bit hard to compute. What do Xiolians think? I don't know much about Roswell or supposed government cover ups but it's always an interesting point for debate.That's a valid point I suppose, but still far fetched being that sending a drone to 'check us out' wouldn't be very valuable to anyone as by the time the data was taken back to the Aliens, they or indeed their planet would be dead long ago thanks to being light years away.
When they sent it they wouldn't have been able to predict if there was even life on this planet. They certainly wouldn't know how advanced we might be. Especially since the distance means that by the time they make it here, earth will be much more advanced. Say they heard us testing nukes in the 50s, we might expect a couple of thousands of years to pass by before they reach us.
Now assuming they decided to send out some drone ships anyway, this would mean that they must be stable, capable, and concerned enough with the very long term. If this is the case, they might be concerned with proliferation of their technology.
Once they have scouted us, and sent information back, it would be thousands of years at least before a fleet, or exodus could reach us. You could imagine they would take extra precaution not to screw up thousands and thousands of years worth of work, planning, and effort than just appearing in the night sky, usually over the Southern US states to towns of hillbillies.
I think there is life out there, but I just don't think it's capable or interested in sending flying saucers to us.
