Can't restore iPhone without signing into iCloud?

I have an iPhone 5c that runs iOS 8.3, and I've been trying to reset my phone. When I went to, it told me to turn off find my iPhone, so I tried, but it said I needed to sign into iCloud in order to do any of this. I don't remember my iCloud account. At all. Is there ANY way I can reset it without this stupid iCloud stuff?

Youre icloud is the same id
for what you use to download apps from the app store

No. You must have your iCloud ID and password to reset the phone.
