Naw!!! We are rare, so rare that we might be unique in our solar system, galaxy! We don't look little and instead the reason for the whole show! "Where is everybody?" -- easy, we're it. Soooo, what's the reason??

The whole event is likely to be an exponential, and the last, ah, after Newton, Maxwell, Einstein, Schrödinger, biochemistry, ..., computers, we look like we're at -- a standard for exponential growth, e.g., the question P v NP -- the unique big turn up out of the atmosphere ... blowing past Andromeda at 0.5 c and accelerating.
