Will Smith talks about meeting president Obama and his son questioning about whether or not there are any actual aliens. Obama makes his point very clear as he addresses Jaden's curiosity of Obama being very clear and serious about the actual presence of aliens on planet earth and them meeting with government officials.
Now these aliens that Barack Obama is referring to, could very well be entertaining a child's imagination. Or there could be great meaning to behind the actions of how he addressed Will Smith's son. Will Smith also professes to have been briefed about the actual existence of aliens during his movie shoots and says he is one hundred percent sure he knows whether or not they are real or not.
