Therapod

This is a sketch of an original work fiction © Us:

1. The story is one of first contact and a central element is that the evolutionary line on Earth is a deviation from the "normal Saurian line" for the development of life on planets like it.
2. The density and history of planets with life and intelligent life in the universe generally are elements. The former is given a value on the conservative end of the orders of magnitude between 1 per "galaxy like ours" and 4 10⁴ which was Drake's original figure, e.g. say 5 for the per galaxy count and 10⁶ for the galaxy count which is 50 million worlds where life has independently reached the stage of scientific civilization.
3. The next element is the fraction that have past the Omega point, the technological singularity, the final stage of [:en:Metasystem transition]], control of culture. Because of the primary plot element, this would have occurred on Earth sometime on or about the time of the Cretaceous boundary event. Assuming a universal time frame and that that would be around the earliest then the implication would be the vast majority of worlds with intelligent life were independently post singularity.
