I'm very serious.

Is that all you have as "argument" ?

Supposing you referred to my comment on the big alien theory, as a biologist, I would say that this pure statistical analysis ignores the possible existence of yet unknown factors that could modulate the probability of existence of alien civilization of different size, planet size or intelligence.

This is why I concluded that this work is based on a pure speculation that these unknown factors don't exist. I didn't say this work is false or bad. I said it won't move us reliably forward on this research topic.
