"Extraordinary claims require extraordinary evidence" (sometimes shortened to ECREE),[1] also known as the Sagan standard, is an aphorism popularized by science communicator Carl Sagan. He used the phrase in his 1979 book Broca's Brain and the 1980 television program Cosmos. It has been described as fundamental to the scientific method and is regarded as encapsulating the basic principles of scientific skepticism.

I think it is likely that advanced civilizations exist on other planets. I am surprised that scientists have not detected radio broadcasts from them yet. Nevertheless, the vastness of the universe and the finite nature of the speed of light impose limits on space travel.
