What I find crazy is atheists who insist God does not exist due to lack of evidence. And then they quickly put on their tin foil hats and tell us that aliens from outer space do, or probably do exist, no evidence required.
That will be because you don't understand and can't see the difference between the probability of flesh-and-blood, material organisms (might be carbon-based, might not be), something at least partially like humans whose existence is in principle detectable, and non-material, supernatural, paranormal alleged so-called entities like gods whose existence isn't even in principle detectable by any scientific means and for whose existence nobody can provide any methodology at all.
I can't say that I believe in alien life as I have no evidence to do so. I can say that I know exactly what it would take for me to be presented with evidence for extra-terrestrial life, which is vastly more than you can ever say for any 'god.'
As with all theists, your parochial village mentality is showing.
