Building buildings

We need engineers to build our buildings today.
How about in the past? As in the way waaaay past. Especially during the egyptian times. There were many compliements on the great pryamid being near structually perfect-the angles were perfect, the size and shape and bricks were perfectly straight and so on. Same goes for some ancient civilization (i think the name was Inut or something. Some "I___" group.)They built stone walls with perfectly straight bricks. I even heard that the blocks used by egyptians were placed so close together that you couldn't even slit a razor blade in between them! Hah, but considering they had no cement at that time..
Imagine building your own lego blocks and stacking them up. Firstly how do you get the damn blocks to be so straight? Ok if they looked straight putting them side by side would probably show some gaps.
Again, wah. Really straight.
What's even better is that they(some !##$^%#$ologists) found a dead cat in the pryamid. It's body was intact,but it wasn't rotting or preserved. It had been dehydrated(which means that it's a dry corpse). Some guy decided to try out an experiment by making a similiar and smaller model of the pryamid and placing a dead cat in it. The result was the same. Other things like plants growing faster(or something) and animal's wounds healing faster in the pryamid were also discovered.
Which led to conclude that the pryamid's structure had been made in a way to channel some energy from who knows where. Well, this wasn't said by me. I read it off the internet-here's the link.
I can't find the damn link, but here's another one. For the sake of putting a link and those who picked up interest. Another link
Well i have a theory however. A long time ago lotsa people built with precision and straightness(i guess) but without modern equipment, they probably had something that can be used to measure straightness that was available in the past. Let us think.
What do they have in the past?
The first thing i thought of was the water level. Water level is always straight inside a cup right? Like in the middle, forget about the sides(curving upwards or downwards).
But i thought of how the egyptians would use it. Take a test tube? They probably didn't have clear glass at that time.
Then it came to me today. The straightest thing that can be made and you don't even need any other tools.
It is the marvellous and common sensed shadow that everything can cast. If they were to set carving out blocks exactly at noon(or some regular time), they would probably have some time to at least trace out the shadow and use it as reference to build blocks. Same goes for planning out the base of the pryamid.
Well more to come soon. I have to play DoTA now! lol.
lollol.
