If you want to log in then put your appropriate email address if you have signed in with the help of your email address. If you have used your Facebook/Gmail then use it according. I think you are somehow getting confused about your login details. So please recheck it and I think your problem will get solved.
I hope this answer helps. All the very best for your future endeavors!
