Thanks.
So you say.
My point, IIRC, is that they are either natural or they are manufactured. If they are manufactured, then obviously, it’s not by humans.
But all the talk about ancient ruins leaves me with one question. People continually say “There will be nothing left in 10,000 (or however many) years from now...”
I call BS on that one. There is one thing that simply would not decay or erode.
And it is one of the first technologies that humans (presumably others also) would have.
Ceramics.
Coffee cups.
Toilet seats.
Computer chips.
Stuff like that.
If man was destroyed, there would be plenty of evidence left for millions upon millions of years.
They might not have any of our writing left.
But they would know how big our asses are!

years ago while excavating on a construction project, some white spherical objects were uncovered several feet down. They were of a ceramic, nature fine, smooth grained and tennis ball sized. There was intense speculation in our news paper on the origin including just which group of native Americans could have created them.
They were sent to university anthropologists and they allowed their differing opinions that pretty much agreed they didn’t know who made them or what they were...... maybe ceremonial.
In the end, an old geezer came and looked at them and declared they were used in an industrial ball mill to produce fine powder from chemical precipitates. Somehow, they had been dumped on the site many years ago
