Are you me? I also don't have access to my first Google account but it forwards all of its emails to my current one.

I can confirm it works as well since someone sometimes fat fingers whatever email address they use for car repair and I get the invoice for it due to Google not respecting the dots in the email address.

My master plan is to get hired at gmail just so I can click the admin reset password button and get access to that account directly so I can finally see the very first emails I ever received.
