How do extremely difficult vanity addresses get found in the first place? I haven't found a specific answer to my question so please excuse me when an answer is somewhere out there.
Regarding the '1BitcoinEaterAddressDontSendf59kuE' address. If it would take more than the universe's time to crack such address how did this address get found and by whoem in the first place? Not any and all combinations of characters is a legit address or am i wrong?
Really confused about this, hope someone can clear this out for me!
And are there more longer known messages in exsisting addresses? Love to know about them!

Edit: What I refer to is a burn (lost key) address instead of vanity (owned key)
Thanks in advance
Funds are spendable by public keys and addresses contain public key hashes. Vanity addresses are created by hashing lots of public keys until the hash is in an expected range. What you mentioned is an example of a burn address, not a vanity address. Burn addresses are crafted by manually editing the public key hash with a specific the corresponding address in mind. Burn addresses do have corresponding public key(s), but since we it is impossible to find the public key from the public key hash, burn addresses cannot spend their funds. They are similar to addresses whose owners mistakenly deleted their wallets, where the funds are in a locked state.
The last digits of burn addresses is random is because addresses also contain a checksum which is the hash of everything else encoded in the address.
