Well, if we are going to assume it was an ancient Martian structure, I doubt it would have any sort of 90º angle or straightness left to it. It would have to be hundreds of thousands, or even millions of years old. Just look at what has happened to early Roman structures in a couple thousand years here in a lovely Mediterranean environment. Add in a more hostile environment such is on planet Mars and you've should have a vastly deteriorated remnant leaving behind only seemingly straight lines and rough (at best) right angles.

Just out of curiosity, because I've honestly not done a lot of searching yet, is there a lot of discussion of that on these boards? I'm still fairly new around here. I've always been quite interested in archaeology. I've read in a few threads about ancient civilizations being "technologically advanced," but I'm not sure what folks mean by that. Do people actually think they had computers? Just curious.

did you read my post to you?
and i think he made the point that the wear and tear of the martian environment, would do much more damage to any organized structure, so even basalt columns would end up looking like battered chunks of rock. i don't think that's either pro or con on the topic of it being constructed by sentients.

So are you saying that, due to deterioration, an ancient structure would be indistinguishable from a natural formation with similar straight lines and right angles? What basis then is there to conclude it is an ancient structure?

"We have seen some evidence that there is a possibility of some life on Mars in the past, so there is probably life all over the universe," astronaut Mark Kelly told a news conference in Tokyo on Tuesday, where he was joined by other members of the Discovery crew.
"From our experience, it is very difficult to travel through space, and I personally think aliens have not visited our planet."
I just want to remind folks a shuttle captain said recently there was life on Mars.
Don't think he was speaking of single cell paramecium either.
