I started doing a math problem and I found the answer to it without having any idea what that answer is beforehand. Does that not mean that I discovered the answer?

If you roll a dice "a" times, what is the probability that you get "b" sixes or more, assuming that b<a?

I have a question I've never seen an answer to. How do you actually carve out two ton block of stone from the rock without using modern boring machines, explosives and whatever else? How in the hell do you do that with copper tools?

>inb4 it was limestone which is softer than granite

Yes but still, how do you even do that with softer stone? And you have to do that for two MILLION blocks. And not only that, I think the pyramid of Giza also has some parts of made from few granite blocks.
