【If aliens on earth is real...even if they came only in 1947, not earlier, don't you think that they have already learned how to understand, read, speak, and write English, if they are really smart as has been supposed to be? If they can understand and write English, don't you think they know how to get into our internet? If they know how to type English and get into our internet, are you sure among all the "people" that are arguing, talking on the internet, there is no aliens????】
