‘Time traveller’ from 2030 meets himself 40 years in the future

The man (or men) claim to have proof both men are him. Yeh, I'm confused too.

We have officially reached peak time traveller. Following a host of people claiming to come back to the future on Youtube channel ApexTV, a man is now claiming to have met himself. It follows a man claiming to come from the year 6000, another man saying he had seen something horrifying in the year 8973, and another saying there was more 'photographic proof'. Noah Novak (the same man who 'passed a lie detector test' on his being a time travller) says that some of the information 'proving' they are the same person is 'classified' so the government isn't able to track him down. https://www.youtube.com/watch?v=0ov_5g4DBaM However, he says that he can reveal some details of their lives, as proof that they are the same person. "I believe that he is me from the future," Noah from 2030 said in the video. Adding: “He showed a bunch of personal information, he said a bunch of things about what I did, he said all the sequence of events and stuff since I came back from 2017. “He said everything that I did, and this is the type of stuff that someone would have to stalk me for my whole life to figure out. "Obviously it would be really hard for him to figure out all of this information. “There is no way that he could figure all this out unless he stalked me from the very beginning."

Noah from 2070 chirps in later in the vid to say that those who travel through time are fitted with 'microchips' that prevent them from saying things that cause a disturbance in a sequence of events (another excuse for not providing evidence).

My main question here, though, is 'if they are the same man, how come they both look completely different?'. Answers on a postcard from the future, please.
