Have aliens been to the earth in the world?

Yes! Dinosaurs and apes appeared at the same time Scientists speculate that a long time ago, an alien flying butterfly broke down and was forced to land on the earth. Because they were threatened by dinosaurs, they killed all the dinosaurs, which was the reason for their extinction, but apes didn't kill them, so they were used for artificial insemination experiments, thus boldly speculating that blacks were descendants of aliens; Yellow people are descendants of aliens and monkeys; White people are descendants of aliens and a tall white ape, which is why humans are smarter than any other creature on earth. Because they all inherited the wisdom of aliens! I hope it will be adopted. Thank you.
