Evidence for ET?

[Anomalocaris]

Is this the same idiocy as “were you there”?

Just wondering if you had any kind, any at all, of a basis for your claims.

If I am not mistaken, I don’t think anyone has made a bottom up census of free floating planets because there is a huge gap in difficulty between finding exoplanets orbiting stars and objects other than stars free floating in interstellar space. We have the theoretical capacity to detect free floating planets only under special circumstances. For example if there is a Jupiter like body half way between the sun and alpha Centauri, we would be hard pressed to detect it even if we know where to look. We also don’t have widely accepted basis to extrapolate from the number we can potentially detect to how many are actually there.

So we only have top down estimates, based on our understanding of interstellar condition, calculated chances of objects forming, and estimate chances of planets formed around stars being ejected.
