Jesus warned his disciples not to believe false reports about his return, because everyone will see him when he comes.

Matthew 24:23-28

23-24 23-24“At that time people will appear who will falsely say that they are the Messiah or that they are prophets. They will perform many kinds ◄of miracles/of things that ordinary people cannot do►, in order to deceive people. They will even try to see if it is possible to deceive you people whom God has chosen. So, at that time, if someone says to you, ‘Look, here is the Messiah!’ or if someone says, ‘Over there is the Messiah!’ do not believe it! 25 Do not forget that I have warned you about all this before it happens. 26 So if someone says to you, ‘Look, the Messiah is in the desolate area!’ do not go there. Likewise, if someone says to you, ‘Look, he is in a secret room!’ do not believe that person, 27 because just like lightning flashes from the east to the west and people everywhere can see it [SIM], when I, the one who came from heaven, return again, everyone will see me. 28 When I return, it will be as obvious to everyone as the fact that wherever you see vultures gathering, you know that there will be an animal carcass [MET] there. (OR, Just like the vultures gather together wherever there is an animal carcass, God will punish sinful people wherever they are.)”
