A know-it-all!
The most common term that is used for a person that thinks they have the answer to everything is a 'know it all.' No one has all the answers to everything.
A person who appears to know everything is sometimes called 'omniscient' meaning infinitely wise or smart. If someone only 'thinks' that they know everything, but they truly do not, then they are simply naive, egotistcal, or ignorant.

You know who you are and your loyal friends know who and what you are so ignore someone that thinks lesser of you. You could also face the person and say that each person does not know themselves 100% so they have no idea what type of person you are.

Yes, I know that for a fact. Do you want to know how I know this, because I am a person and I know EVERYTHING.
A "know-all" or in US a "know-it-all"
No, it is impossible for someone to know everything because there is too much to know.
I don't because us Americans have something in our brain that thinks we need to know everything we can.
