but they said the pyramids were built in 20 years.
That was one pyramid... the great pyramid of giza. Not all pyramids.
The reason we believe humans built the pyramids without advanced help is because we see an evolution of trial and error among their construction. We see early crude mastabas, then we see stacked mastabas, then step pyramids, ect ect. The bent pyramid offers a great example because it's incline had to be changed part way through construction in order for the base to support it. If advanced beings were helping here, we wouldn't expect to see representation of inferior pyramids, or architects making mistakes and learning from them and then changing their techniques over decades and decades. Archeologists are used to determining if a technology or skill was introduced from outside lands or is indigenous to the people. We do not see the typical signs you see when outside knowledge is suddenly introduced, and instead see a process of human learning and improvement. There is a reason we do not here seasoned engineers and architects who are used to planing great projects and seeing them through saying the pyramids were impossible to build for the logistics of the time.
might need a few hundred thousand "volunteers"
I encounter christians everywhere. At work. In my neighborhood. At the store. Even in my own family. I have never run into a dangerous gang or gang member in 28 years though. I have heard things happening scarily close to me at times, but never directly.
Hi Oly, I think this is a great question and you stated it in a non-assuming way. I think neer gave a good example of greased rope coated with sand making a precise cut, given enough time. You would have to be more specific about which cuts you are curious about to get a better answer, but it's nice to see you engaging in intelligent inquiry.
yes i agree heph has got more inteligent since questioning his beliefs , ( pats him on back ) .
