old ipod touch

so i had this old iPod touch years ago. its the first model of the iPod 5g. i thought the iPod was gone, until i recently moved and found it. well the iPod had to be restored which i did with my desktop, but now i have to put in that apple id and password to get into it, which i don't know anymore. its different from my current one because my dad is the one set it up for me when i was little. is there a way i can completely reset it so i can use my current apple id on it? I have a kid who loves to play games on my phone, if i could just fix the iPod, it would save me a bunch of money and time.
