oh really too bad there wouldnt be windows 10000 years ago bitch. and what doors? does it look like they knew how to make hinges and shit, thats metalurgy.

[baetores]

Well if one thing is proved, it's that you don't have any civilization when I look at your tone. In the hands of people like you, every metal object would be a dangerous thing.

[SirGnork]

Don't start with fruitless insults now. I think you are right, anyway.

[Christmas800]

wow. re-read your comment. it makes no sense man. seriously i just want to know what you mean

[ioitiub]

[godofwar303]

Wow a quarry underwater.

Besides there are no big structures on yonaguni island that were built with it.

looks like a collision of two walls during a volcanic eruption, you can tell by the pillow-like rocks, those used to be magma and lava after coming in contact with water over time. This effect resembles oil in water.

As it does to numerous others, including geologists and some historians. If they are naturally occurring then it is amazing that all of these phenomena have occurred in the same 120m square area, and nowhere else around Yonaguni or the Ryukyus.

looks like a natural geological formation to me
