Well look at us!
It’s clearly not a scientific position to take a singular example and extrapolate a universe, but there are surely certain baseline criteria for existence. For instance, everyone of us alive today is the ancestor of survivors, and I’m not being trite, this is vitally important for a number of reasons.
Psychologically it gives us a superiority complex, we’re survivors right, winners, and to the winners the spoils as everyone is aware.
But at the expense of true species introspection, because all those peace-loving navel gazers got rolled by our two-timing psychotic violent forerunners, and always will. Something like 16Million men from the Pacific through to the Caspian sea are said to contain DNA from Genghis Khan (

The upshot of this type of selection, is a species that will brag of it’s rise, consider that this was what it was born for but not realise that it has inherited a dying graveyard, with an over extended population and depleted natural resources until it is too late.
Too bleak a prognosis? I mean we are all moral people, able to see and condemn the failures of those before us, join Greenpeace and Amnesty, well look at the current crises, where were those morals in the people who stripped the shelves clean on pandemic day one?
We are governed by biological imperatives, It would be no different anywhere else, evolution would produce beings with survivability the same as fire ants, Cane toads and viruses, but if we are let loose from the constraints that normally hold our population under control, we will breed until either we consume all, and starve or some other organism arises and uses us as the foodstuff or vector of reproduction.
That is why I think there is no spacefaring races, they did as we are doing, and died before they got there.
