I can accept the possibility of life on other planets. It happened here on Earth, so I guess it could happen on other planets. However, that does not mean those creatures are more advanced than us.
If there are sophisticated beings living elsewhere in this universe, why would they want to visit us? We seem to be driven to fight with each other and destroy our own planet.
I can hear the alien adults telling their children, “Stay away from Earth, that’s a bad neighborhood.”
