I think I should elaborate my point.
Whatever knowledge people in the West or East had say 3000 years ago, it did not have the same disciplines as you mentioned in your post (and the list was no complete). These disciplines sprouted centuries after and were established in the Western format.Right
The natural factors generating knowledge in the Universe were at work 3000 years ago as they are at work now. These factors work independently whether human beings are ignorant of them or are know them.
Hence we may conclude although these sources did not exist in their current format 3000 years ago, yet the Universe existed with generating the facts in it, so the Knowledge was there.
Does it help bringing us on the same page?

Like I said, we're saying the same things. The data has always been there. The difference between ignorance and knowledge is discovery. That's all.
And for the record, of course my list wasn't complete. You had asked for breaking it all down into three or four sources. My point was that what you had asked for silly because there are thousands of sources, each with thousands of subsets.
It's not just me who is confused by your use of the word knowledge. We attain knowledge and understanding - it's not some ethereal thing just floating out in the space that we can go and grab. It's not a finite object that is attainable.
We learn and make discoveries based on experience, experimentation, and, well, a whole lot of other ****. We don't take bites of one giant source of "Knowledge" - we gather and learn, and the results of those experiences create knowledge. If, for example, mankind just suddenly vanished from existence, then the only knowledge on this planet would lie in the minds of the remaining higher mammals, who may, over the course of their grand evolutionary journey, discover different answers to the same questions that we have discovered for ourselves - thus, their knowledge would be different.
Do you follow?
knowledge is not a proper noun.
