I've read alot about unusual and unexplainable archeology.

While I don't deny it exists, there are other problems.

Where are the mines? Where are the roads?
500,000 years from now, even if man is wiped out in the next 20 years, the evidence of man having been here will still be unmistakable and irrefutable.

So while things like this are anomalies, and certainly raise way more questions than they answer, show me some infrastructure!!

The delivery system for 'transpermia' don'tcha know! There use to be pix on the net of these things taken in S. Africa and in Czechoslovakia.

"...500,000 years from now, even if man is wiped out in the next 20 years, the evidence of man having been here will still be unmistakable and irrefutable."

But not in 2 to 3 billion years, a relatively short period of time in respect to the Earth.

Yup. Our toilets will last almost forever.

Slow down and chill. You will learn all in good time. Supposedly, the Andromedans and the Pleiadeans have our back in all this. We are royalty to them. Ever wonder where our unexplained strands of DNA came from? (222 in all) Now you know.

Sit back, watch and enjoy the great fireworks in the sky soon.

I know, you want to know when all this will take place. Sorry, they never sent me a memo from the astral plain main office, and certainly wouldn't confirm any dates anyway.

Even after 50 years roads can practically diapppear. There are just a few wooden buildings 1000 years old. The pyramids and the Sphinx are probably less than 10,000 years old. Stone erodes. Dust settles out of the air and buries stuff. Anything organic gets eaten. In a million years there is next to nothing left except a natural terrain. If we could excavate the entire surface of the planet 200 feet down, we would no doubt see some interesting things, but most artifical things are long gone. It is likely that most civilizations cannot thrive if they migrate to a new climate, as Montesquieu said, and this bodes ill for extraterrestrial civilizations that leave their home system. Maybe some ETs have blown through the solar system, and maybe there have been intelligent, industrious beings on earth a long time before now and maybe many times, but to last more than a few thousand years is probably a rare thing in the universe.

How about the same principle as a shot tower?

The answer is not archeology but rather mineralogy. The spheres are bubbles that floated up through the prophylite

I doubt you are going to find any remnants of 2 or 3 billion year old infrastructure. Even rocks that age are not real common.

Depends on the critters evaluating the evidence.
