In theory, if scientists could nurture an Einstein clone and teach him about himself, all of his known theories and all that we know he Studied do you think he would be able to give us his Theory of Everything?

I doubt he'd help us much more than other scientists would. A clone of Albert Einstein wouldn't be Albert Einstein. Although he would have the same genetic code as the original Einstein, he would be subject to different epigenetic influences in the womb due to him necessarily having a different (surrogate) mother in this modern era. He would also have different life experiences growing up which would further cause his brain to develop differently. For all we know, Einstein 2.0 might develop entirely different interests and not care about physics at all. All else being said, we can't predict what it would take to develop a theory of everything. We might be on the cusp of developing it right now, it might take another 200 years or we might not be smart enough to ever figure it out.
