Satoshi Nakamoto registered Bitcoin.org using Anonymousspeech.com, a privacy-focused domain registration service, on August 18, 2008 -- over two months before the official release of the Bitcoin whitepaper on October 31. It is the earliest known public timestamp associated with the inception of Bitcoin, suggesting Satoshi had been working on the project well before going public. The domain would host the whitepaper, software downloads, and serve as Bitcoin’s home on the internet for years to come.
