What are my options for setting up a Spore account?

[lyric python]

I bought the game on steam all the way back in 2015, but I used an old email account I don't have access to (tried to regain access on multiple occasions to no avail), so I don't have access to the receipt to use as proof of purchase (not a recent purchase so can't press the button to see the receipt over at purchase history).
The CD key window is empty (the one you get if you press CD keys under "manage" on steam), and I've tried the regedit trick but it shows %CDKEY% in place of a key.
EA app doesn't pop-up to ask me if I want to link the game to it on startup (although I did link some games, seemingly randomly like Mass Effect 2 but not 1).

The only option I see right now is persuading steam support to give me the keys. Is there anything I'm missing?

I thought steam kept your entire purchase history. Mine has every game I ever bought or gifted.

But if it’s not there then rip

Contact steam support to see if you can get receipt from them

i do have spore on my purchase history. the way i understand it, steam app can show the entire purchase history (must click 'load more transactions, otherwise same thing as on website), but steam website only shows the "recent" purchases (only goes up to 2022 for me). the 'i would like to see or print the receipt' button only appears for the recent purchases, so not for spore for me.
