Welcome, I am Cory. Thank you for asking your question today.
When you do not sign into an account for more than 180 days, it is purged from the Gmail system. After it is purged, then it can be used by another person signing up for it.
If you can not reset the password ***** the site here https://accounts.google.com/signin/recovery then it is possible that it is registered by another user.
I hope I have answered your question today.
Please let me know if you have any other questions.
