*) If you know your old gmail account password go to gmail login page ( watch this video - How to Sign in to Gmail ) then use your old password and you can log to your account

*) you can't create same email two time that's why gmail website said "account already exists".if you don't know your password Try I can't remember my password ( watch this video - How To Reveal Forgotten Gmail Password )

Yes, it would appear gmail assigned you a new account.
To Delete the NEW account from Google:

1. Sign in to the NEW account at accounts.google.com.
2. At the top, click Data tools.
3. In the Data Tools box, click Delete products.
4. Click Remove Gmail permanently.

Now, to get into your OLD gmail account through your new smart phone, you first need to delete the NEW gmail account from the phone. I do not know what kind of phone it is, so I suggest you go into the store where you purchased the phone and ask for assistance.
Apparently, incorrect selections were made while attempting to put your OLD gmail account into the phone, and Google assigned you a gmail account based on your name. It is similar to the old account name.
The specifics of your phone's operating system prevent me from knowing how to properly help you. But it's obvious you need to delete the NEW gmail account, install the OLD gmail account, so when you tap the gmail icon, you get what you want. The people who sold you the phone will be able to help you the best.
Sorry I couldn't do more.

You don't need to setup a new account just sign in with the old details

Go to gmail
Type in your user ID
Then toward the bottom of the page
Look for CAN'T LOG IN TO MY ACCOUNT
And follow the prompts

Maybe, try setting-up a second Gmail account, then send transfer) your emails from the old username account to the new username account. If this works, then either try deleting the messages from the old gmail account and transfer the messages from the new gmail account back to the original gmail account ... or ... just delete the old gmail account if you successfully transferred them to the new gmail account.

Point your web browser at http://www.gmail.com

If it comes up with your new account, sign out of it by clicking the avatar in the upper-right then clicking "Sign out." Go back to step one.

Now on the Gmail sign-in page, click the "Can't access your account?" link.

you have create new facebook account an add as friend

the only way I know is to master reset it, create new google account or use the previous one to activate it.
