Consider, too, the revolution in understanding that has taken place since the mid-1990s regarding planets and moons in solar systems well beyond ours. Since ancient times, natural philosophers, then scientists, and untold interested others predicted, assumed even, that many other planets orbited their stars. By now thousands of exoplanets have been officially identified.

Scientific facts that prove the existence of other life forms in the outer space
Consider: The rover Curiosity has firmly
determined that ancient Mars was significantly more wet and warm, and was an
entirely habitable place for microbial life. All the ingredients needed for
life as we know it – the proper chemicals, a consistent source of energy, and
water that was likely present and stable on the surface for millions of years –
were clearly present.
Did microbial life then begin? If so, did it
evolve? Those questions remain unanswered, but this much is known: If a second
genesis occurred on Mars (or on Jupiter’s moon Europa, Saturn’s moon Enceladus,
or anywhere else in our solar system), then the likelihood increases
substantially that many other forms of life
exist on those billions of exoplanets and exomoons now known to orbit
distant stars and planets. One origin of life on Earth could be the result of a
remarkable and inexplicable pathway to life. Two origins in one solar system
strongly suggests t hat life is
commonplace in the universe.
