You must have a LOT of rather BLIND faith in your construction on reality.
OR perhaps you just have a huge, intense bias toward a TYPE I error instead of any concerns about a TYPE II error.
In an age when it seems no one can keep a secret, I am willing to bet a few bucks that if there were real aliens, or their remains, we would be seeing them on Fox News.
By the way, what are these error types, I and II? I never heard of them before.
