Of course not.
But...
I know the one who knows everything.
Grandpa used to say " it's not what you know, it's who you know". The notion that you must know everything yourself is a modern education notion, and false. Know where the answer lies and you don't need to carry it with you. You can't. And thats ok.
Who is the best source of answers? Well the creator of course! And he is just waiting to discuss the mysteries of the universe, or the difficulties in your life. Ask him.
Do I know everything? Nope. And that's perfectly ok. Sometimes people think that I do, or think that I think that I do. But neither are true. If someone asks, then I have an answer. Sometimes from my own accumulated knowledge, sometimes through study, and sometimes through direct revelation from God. Just because I can provide an answer does not in any way mean that I "know" everything! What a silly notion. But I do know the one that knows everything. Often times I am learning as I speak. God speaks and I listen along with the question answerer. I do not "know" more than them, I am learning alongside.
No human knows everything, but every human can find all the answers in the creator who loves to share truth. Ask him, expecting an answer. Seek him, open up to him, share with him, and you can learn everything and anything.
Know the one that knows and you will never be without.
