The biosphere is about 3,800 million years old.
Trilobites were one of the dominant species for over 250 million years.
Dinosaurs ruled the Earth for 200 million years.
Humans are about 2.5 million years old.
Homo sapiens are about 0.3 million years old.
Human agriculture is about 0.012 million years old.
Infancy.
As for life in the universe, I already mentioned the universe's young age as compared with its productive (by our standards) lifetime. It's approximately, and conservatively, in the first hundredth of its life. An infant.
Humans may not ever master interstellar distances, but I figure that somewhere and somewhen species will emerge that conquer space in ways perhaps not even dreamed of by science fiction writers. There is a ton of potential for advancement. If humanity fails to successfully expand into space then that would make us early "prototype", like 78 rpm records. Good while it lasted, but doomed. If humanity manages to solve some of the more difficult issues related to consciousness and space travel, then they could be some of the universe's great pioneers.
You think space travel is a sign of adulthood? Why? And why should one species be more intelligent than others?
Yes, the ability to go out and reproduce is generally seen as a sign of adulthood. Many do not believe it would be "reproduction" if the Earth sends informational packets of parts of itself with 3D printers that use the materials of other worlds to create copies of itself. That's because they think humans are
special. It clearly is reproduction, though, but humanity/the Earth has not reached that level of development.
BTW, you did not address the information above which basically seals the deal that the universe and its life are in their infancy. Unless one believes in the Biblical Armageddon, of course.
