Did Proxima b’s Scientists Visit Earth Before the Pyramids? #Paranormal

It is conceivable that the Earth-mass planet Proxima b, which lies in the habitable zone of the nearest star to the Sun, Proxima Centauri, hosts a civilization similar to ours. Owing to minor differences between their and our history, it is possible that they had reached our current technological state slightly in advance. Consider a tiny margin of head start for Proxima b science, of order 0.00002 of the age of the Earth. This amounts to 100,000 years, meaning that Proxima’s astronomers had used telescopes to discover Earth a hundred millennia ago, in the way that we discovered Proxima b…

It is customary to search for signs of life on rocky planets in the habitable zone of their host star. There, the planet’s surface is not too hot or too cold, allowing for the chemistry of life in liquid water in the presence of a sufficiently dense atmosphere. One could imagine that other forms of life-as-we-do-not-know-it thrive in other fluids. NASA’s Dragonfly mission, scheduled for launch in July 2028, will search for signs of life in the liquid oceans, lakes and rivers of methane and ethane on the surface of Titan, a moon of Saturn. The surface temperature on Titan…
