Could you clarify a little bit here? It would be good to know what you mean by:
"Where should I go..." - are you talking about books, online resources, or perhaps studying history at a college or university?
"...from the beginning..." - are you talking about from the start of 'recorded history'? Are you talking about global history? The history of specific areas or peoples?
"...where to start..." - this relates to point 1 above.
TBH, no historian knows history "from the beginning". The past is a vast landscape, about which we can only understand fragments. Professional historians tend to be specialists, although there are some mega-space-brain types who have command of multiple sub-fields. Clarifying where you want to start and what exactly you're interested in would be really helpful.
