Could the human race have originated from another planet?
Did humans come from another planet?
Is there other planet like this world with humans? Why did humans come to existence? Why did humans come into existence? Why didn't any of the other planets in the Solar System evolve the conditions for life as we know it, given that they were created by the same process? When did life originate on our planet? How many humans have been born on planet earth since the beginning of time? Was it due to some evolutionary flaw that humans are completely different from all other species on earth? Why were humans created? Why other species on the earth have not evolved as human? Humans evolved from apes and apes still exist. Has this happened with other species, when the species co-existed with its evolved form? Is it true we were really brought to earth by aliens? Within the next century, will humans discover life on other planets? Is it true that we have discovered a ninth planet in our Solar System? Why are we on this planet? If all the humans left the earth and came back after 100,000,000 years would the chimpanzees/monkeys have evolved and built technologies like ours? Did human evolution happen already? What would it be like, had there been 2 intelligent species on earth, rather than just humans? What is our planet? Are we human beings aliens to planet earth? And if not, then are we acting so? Why were humans born? Have aliens not contacted Earth because they've fulfilled life's meaning, and become one with pre-universe? How did humans evolved? Do planet X exist? Is there life on other planets and are they more advanced than us? Which planet is considered as the earth's twin? How important would be the finding of another planet in our solar system? Have aliens been to the earth? How many human beings have lived on this Earth since the beginning of the time? If we found a habitable planet but it already had sentient inhabitant, would we try to conquer it? How would society respond if we discovered that there is an interstellar 'human' empire out there in the galaxy?
