All I can think is this scrap drive was everywhere in the fighting world at that time. There were so many interesting autos, tractors and other machinery. And the world lost representative designs. I guess we survived it. Just wish the machinery they used to cut the millions of cubic yard sized limestone blocks for the pyramids could be found.

I think they used lasers. or possiably the exhaust from the starship was used to do it. or the phasers

It had to have been dental floss. That stuff cuts anything...

All I. Just wish the machinery they used to cut the millions of cubic yard sized limestone blocks for the pyramids could be found.

If we ever actually do make it into outer space, we may find out more about how the pyramids were built than we want.
