I could summarize any discussion about it with two words "no evidence". We are the only statistical example of life on a planet, so there is no basis at all for even an estimate.

That there are a huge number of stars in the universe is not evidence of anything. It could be that the conditions needed are so numerous and rare, that Earth is the only one. It might be like picking a specific card from a shuffled deck 1,000 times in a row.

There's evidence, it's just modest. I recall the outcry around here when it was pointed out that the number of known exoplanets was going to increase by multiples due to the improvement of observatory technology. Speculation is, there isn't any other intelligent life because you don't want there to be any.

Garry Nolan of Stanford says there is evidence...solid, material evidence. And he has some of it in his lab.

Of more relevance is that those billions of stars are so far away as to make this moot as an issue or phenomenon for us.

“We are the only statistical example of life on a planet, so there is no basis at all for even an estimate.”

Exactly. Every evolutionists’ statistical argument about the inevitably of finding life in the universe fails when confronted with the words “invalid sample size”.
