According to Alfred Russel Wallace, a colleague of Darwin, called it the intelligence evolution. Wallace could not see how Darwin's natural selection could prove how we have evolved so drastically, he believed that the human brain and its intellectual faculties are qualitatively different from anything that had preceded them. He believed that this ginormous gap could not have been bridged through natural selection alone, which is where he believed that there was an unseen creative spirit of all life on Earth. He believed this spirit came down to Earth three times: First to create life from inorganic matter; Second was when animals achieved some kind of consciousness; Thirdly was when humans achieved the same kind of mental awareness that we have now. He believed that this wasnt just random occurrences like what Darwin thought he believed that this changes had a creative intelligence behind it.
This unseen creative spirit could easily be an extraterrestrial that was curious in our biology. The belief of our "creation" could possibly be the moment that extraterrestrials came to Earth and made us in their image while keeping our individuality.
