Message:So early earth besides being Goldilocks, besides being seeded with nucleic acid from Mars, besides all the other rare and unimaginable circumstances, now has one more.
We got rammed by Theia. Didn't know it had a name. Part of the earth on impact would be ejected to form our moon. (Needed for life.) But also the iron core is a result of impact. Iron core protects us from solar winds. Other rocky planets don't seem to have one. Theia collision ejected mass out, made a hot crust to contain the innards and sunk massive amounts of heavy elements to the core. Yet there are irregularities (discovered in 1980, recently explained) which models now predict appear post collision.

Add to that that our angels and you really have Terra v Sol being the entire intelligent life in the Milky Way. Could be some in Andromeda which gets here in around five billion years. But scour the Milky Way and you'll not find even a cabbage that squawks when you kick it. If there is going to be aliens, it will be from humanity expansion and millions of years of Darwinian adaptation.
Science makes Earthlings special. Take that Cruz, Skia and Cimmer.
