i want to clarify

i heard that there is a banner talking there will be an UFO attacks at anytime on the news in America from a local radio in hongkong.Is this true? And from the radio i listened to, UFO already entered human society, and they have contacted to the national defence of many countries. Also ,it is suggested that there lacks a organization to react to alien attact to the earth and we are quite dangerous if it really happens What would you think about that?
