Yes @D32. I saw that part. But I decided to delve 'deeper' and think about it from a historical and psychological perspective.

Carl Sagan has written this book, 'The cosmic connection' and in it he outlines how and what has propelled humans to SETI. He says that humans have always wanted to understand how they relate with the universe and have always attributed intelligence to celestial bodies like planets.

On the other hand is Enrico Fermi's question: If there's at least one highly advanced civilization that spans into our terrestrial future, why hasn't it made contact with us? Instead it's we terrestrials who are charging into a future that seeks to dominate the universe like in the next 5000 years when we'll be doing things like 'star lifting'.

Now, given the nature of the human mind, for example like in creating projections, isn't it plausible that SETI is a psychological exercise to find and experience the limits of Man?

If this is true, then at least some or most if not all extraterrestrial intelligence is from earth.

The idea that the universe is homogeneous in nature and that the organisms were carried there by currents also introduces a complication on the definition of extraterrestrial intelligence.
