Hello, is it possible to see when was bitcoin address or wallet created?
Thank you
All possible Bitcoin addresses, and therefore wallets, have always existed.

You can only know when a transaction occurred in a particular address, but the address has and will always be there.
Exactly.
This was my first thought when I read the question. The address always existed.
And anyone can prove it just by searching in any block explorer an address created offline. Your address was already there, because it is valid.
You cannot just enter anything because there is a checksum (details
here). So if you enter an address 1111111111111111111111111 the checksum is invalid and that address simply cannot exist.
The only thing that changes is who has access to the private key of an address. That event could be somehow tracked in certain scenarios, but not in a general way.
IMO, you should check the first time the address received any coins. This is the first registry of that address in the blockchain.
But you can find some older off-chain registries. Such as when you send your address to an exchange to make an withdrawal.
