Anyone claiming to be Satoshi Nakamoto is just taking advantage of bitcoin's growing popularity to make it popular as well, but they can't provide accurate evidence, so ignore it.
Although there has been much speculation over the years about who Satoshi Nakomoto is, there has never been any confirmation, and the answer is that no one knows who Satoshi Nakamoto really is other than him.
It also showcases the beauty of bitcoin because of the blockchain that makes its identity undiscoverable.
Actually it's quite simple, He doesn't want recognition for himself and that's the reason why he doesn't want to be known until now because indeed if the only goal was not to be famous he would have easily gotten it from the very beginning of his creation of bitcoin.
For example, such as Vitalik Buterin who created and claimed that ETH was created from scratch, actually Satoshi could also claim it actually but because he didn't want it he didn't do it, so for now why is he thirsting for recognition? no it doesn't really make sense
