Like i said if we do find something. we can always explain things away without further evidence to go by...Soo we say it is nothing..Never adding all the peaces...that is nothing, that is nothing, that is nothing, add them all up still nothing..... you say there would be evidence if such a race existed but would you see it if you seen it? Or would you say it is nothing?
um yeah they tied rocks too thier head it is nothing.
you kind of proof my point..Even if we see something strange and could be said evidence of another race we would just say they tied walks to their heads.
if we see them spraying us we would say it is just con trails...If we see a under water city we would say it is natural rock formations because it would need to be 10.000 years old or older..

you can have your own ignorant opinion...the point is us logical rational people will continue to go with what makes sense based on the evidence we have.
