But if you study these things

you are going to come to different conclusions that when you started
out.

that's a matter of belief...i have seen the last
few years on the net a lot of "evidence" and i am
now even less convinced of aliens visiting earth...

In a way. But "belief" suggests something supernatural which is wholly
reliant on faith. The idea that aliens have been visiting the Earth is a
theory based on scientific evidence and the possibilities it presents. E.g
our knowledge of the Universe itself and awareness of the laws of physics.
It's also based on anecdotal evidence, witness testimony and to some extent
even physical evidence.

In order to remain sceptical in the face of such evidence, means one has to
maintain an idea that all the evidence is totally worthless. However in
order to do that one has to have an alternative theory, belief or a
particular view of the Nature of the Universe. So until there is conclusive
evidence one way or another it's all a matter of conjecture and belief.

But at the end of the day there is more evidence supporting the possibility
than there is of the impossibility. So IMO it is more rational to base ones
theories on possibility because the alternative is impossible.
