The Buried Gate

[Descended]

Any Self Respecting builder who was biulding a two story house for Himself and did not have money issues would build his house out of stone and concrete over steel any day of the week. That is all I'm trying to Say.
Look at the Pyramids, they were biult on stable ground and they will outlast any steel structure our generation has made.

Steel yes... but we know that the Ancients didn't build with steel, they built with a naquadah alloy which has lasted millions of years in various environments on the show. The pyramids would be eroded down to dust in that length of time from simple weathering. Entire mountains weather away, so a pile of rocks is just as susceptible. People think stone will last forever and it will last for several thousand years, but it eventually gets eaten away by water and wind. Stone structures last longer than steel because of corrosion and oxidation, but if the alloys the Ancients use do not corrode at all (or extremely extremely slowly) then they would be preferable.

I think Destiny is made of something else since we have seen signs of corrosion which were not seen on Atlantis, but then again Atlantis was inhabited until 10,000 years ago, while Destiny has been unmaintained for a million.
