I like the tales that asserted that aliens "invested their own destinies " in us via viruses that have changed our genomes (or the genomes of the earlier primates to create the "hopeful monsters" waiting on an environmental condition that is favorable to these genomic changes.
Not so far from a possibility , because several "Pseudogenes" reside on our own string that bear the result of the infection by viruses (tht have left their copies of their own DNA onto a specific string of genes like the GULO genes , associated with our chemical inability to create vitamin C).
The sci fi portions are the implied "bio engineering" that the aliens had performed on us. We shall become more like them at a faster pace as new and weird viruses occur on earth. These viruses are mere "Intelligent Design" tools weilded by aliens who have transcended the very needs for corporeal being. (Sounds like the ending should be "And let there be light", since we become the children of the universe
The other thing was the first writing about Alderson "jump spots" where, like "worm holes" a vessel could cross the galaxy or two by knowing the jump spot road map of the universe. Theres a contingent of cosmologists who say that a black hole will not detroy whatever enters its realm, but will "beam it to the next "node" where two or more event horizons cross.
