Has anyone ever seen Satoshi Nakamoto, does he even exist in reality?

There exists a 'zombie bitcoin' that moved after 11 years.
In 2020, a strange transaction was noticed: 50 BTC, mined in February 2009, were transferred to a new address.
This triggered a wave of speculation because the coins were mined just a month after Bitcoin's launch — meaning they could have been mined by Satoshi Nakamoto himself.
