So i checked back the first incoming bitcoin transfer. But thats doesn`t mean it is the real creation date of the bitcoin adress.
It is the latest possible date.
As I assume that I created this bitcoin adress the same day as the blockchain wallet, so I need to know when the bitcoin adress was created.
So if there any ways with a known bitcoin adress to find out when that bitcoin adress was created?
Remembering the creation date isn't important at all upon recovering your wallet from blockchain.com, and also there's no way to find out when you have created the wallet. It only recorded when there was a transaction to be done.
An email address is very important upon recovering the wallet in Blockchain, if you don't have this, there's no way to recovery. If you have lost 2FA or password there's a possibility that you can brute force your wallet but if your email address were lost. The chances are very slim unless if you remember and have full control of your email address.
I was bookmarked this video youtube tutorial a long time ago, I saw posted here but I can't remember where it is.
Brute-force your online blockchain.info wallet with btcrecover, it could probably help you if that is your problem.
