Comet impact in Sardinia?

[E.P. Grondine]

There was a culture ,a very distinctive one. Like other cultures that were replaced it did not reappear elsewhere.

There are multiple possible reasons for the frequent changes in culture that have happened in prehistory and recorded history that are not related to impacts or tsunamis or plagues .

btw, I have had no access to the site, apart from gobbleygook for over a week .

"People are still searching for answers to questions such as these, for the first inhabitants
of Malta left no writing behind them when they vanished, as mysteriously as they had first appeared, sometime around 2500 BC."

"The archaeological record shows unequivocally that the Temple builders disappeared from around 2500 B.C. Whether this was due to over-exploitation and eventual exhaustion of the natural resources - parallels appear here with Easter Island - compounded by successive years of drought or a climate change, remains speculative. Was the population completely wiped out, or assimilated? A warlike Bronze Age people, similar to those of Greece, southern Italy, and Sicily, succeeded the Temple builders, bringing with them an entirely new culture which included disposing of their dead by cremation."

Again, the last time I looked in detail ca 2006, the exact dates given were ca 2,360 BCE,
followed by a 200 year hiatus.

Note from the very limited content of the links 1) "temple builders " that culture was very distinctive , look at the monuments ,like most cultures that disappear from the record the related material culture did not re-appear elsewhere .
2)"Whether this was due to over-exploitation and eventual exhaustion of the natural resources" two of the many possibiolities neither of which mention the limited evidence free and speculative "seismic tsunami, impact tsunami or impact airburst, and PLAGUE."
3)"Was the population completely wiped out, or assimilated? " assimilated does not suggest "A really big one destroyed Malta ca 2,360 BCE - it left no one alive. "
4)"they vanished, as mysteriously as they had first appeared " No evidence of what happened to them and certainly no evidence that they were wiped .
