Note, the movie is mostly serious factual reports from the 7th century on. Many with fascinating videos of craft.
Rod Serling narrates.
“If each of these stars only had 1 planet orbiting them, there would be aprox. 40,000,000,000,000,000,000,000 planets. If anyone thinks we are the only intelligent life out of all these planets, well let’s just say their egotistical rating is way off the scale or they have the IQ of an ameba.”
Well, if billions of years of evolution is required to produce intelligent life; and if evolution can stall, go sideways, or go backwards (or even be wiped out) in those billions of years; it might take 40 x 10 planets to finally end up with just one where life finally ended up as humans.
It’s a 1976 documentary.
Quite a number of reports I haven’t heard before.
