It's interesting and fascinating that legends exist on the subject of intergalactic wars and battles going back many ages and cycles. It's also an idea that this could be going on now.

In the 1960s some Soviet scientists proposed that the Moon is artificial - and by implication a space craft. The Moon, according to legend, is a recent arrival.
For example:
"..a lot of myths, legends, and tales say that there used to be no Moon in the sky. The Moon appeared after the Great Flood. This was noticed by the people who lived in the south of Greece, as well as by African tribes and others. ... Other sources say that there used to be two or even several moons shining in the sky. ...
The people from the Mayan civilization left reports, in which they said that it was not the Moon, but Venus shining above them in the sky at night."
" Democretus and Anaxagoras mention that there was a time when no moon could be seen in the night skies. In describing the history of the Greek region of Arcadia, Aristotle writes that the Pelasgians lived in the area since very old times; at a time when the moon did not exist.
"According to Zulu legend, the moon was brought hundreds of generations ago by two brothers of alien form, Wowane and Mpanku. "
It may be that the strange sounds pass around the Earth.
"The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. ...They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away... they rang for more than 20 minutes. And yet, it seems, no human felt them...many features of the waves are remarkably weird—from their surprisingly monotone, low-frequency “ring” to their global spread.
Most earthquakes send out waves with a slew of different frequencies, but Mayotte's signal was a clean zigzag dominated by one type of wave that took a steady 17 seconds to repeat...“it's something quite new in the signals on our stations... They're too nice; they're too perfect to be nature,”
This event, that was sufficient to move the island several centimeters, occurred with a low frequency monotone sound that continued around the planet for 20 minutes.
The theory is that there was a movement in the underlying magma - presumably of a type never previously observed.
Still, the monotone nature of the sound seems quite at variance with natural geological sounds as different mineral structures are compressed, sheared, liquefied and crystallized. I wonder whether the war in the heavens is also a war in the earth.
Or perhaps we have a new human player with scalar weaponry providing a demonstration to potential customers or victims.
Jets do not go supersonic over cities and supersonic jets do not produce enough energy to shake London.
Years ago there was a similar noise event south of where I live, sufficient to crack concrete slabs of houses. It too was said to be caused by a supersonic event - in that case far out to sea.
