Scientist Zakharia Sitchin and science fiction writer Alexander Kazantsev put forward their own version of the origin of Adam and Eve, who, according to biblical teachings, were the first people on Earth. Experts suggest that the aliens could have migrated to Earth from another planet, or they conducted an experiment and added thinking genes to the DNA of primates that made them human. According to science fiction writer Alexander Kazantsev, the planet Phaethon was in space. There was a nuclear war and the newcomers who lived there had to look for a new "home". After the planet Phaethon was destroyed, the aliens moved to Earth and began to live on this planet.
Scientists Zacharia Sitchin believes that Adam and Eve were created by aliens who conducted experiments on Earth. Allegedly, the alien engineers decided to find out what would happen if the primates were able to think. Aliens have added thinking genes to the DNA of primates. Then the first people appeared - Adam and Eve. The story that the first people on Earth were Adam and Eve is told in Christian teaching. Allegedly, God created the first people, who became the progenitors of all the inhabitants of the Earth.
Of course, this version has no confirmation, which is not surprising for religious teachings. There are many theories about how man came to be. The most likely scientists consider Darwin's theory, according to which man appeared in the course of evolution. It is already known that human DNA is 95% similar to the monkey gene, but some ufologists, science fiction writers and other people who do not have a specialized education continue to believe in aliens and UFOs.
