My philosophical take on this subject is that Earth had a great "do-over" 66 million years ago, when the dinosaurs and many cold-blooded lifeforms went extinct. If there were cold-blooded lifeforms on other planets on a similar evolutionary schedule, they would be millions of years more advanced than humanity right now. They may even be looking at us as an evolutionary freak show, being warm-blooded when everyone else in the universe is cold-blooded.....
